  • ★★★ How Long Does She Want You to Last? ★★★ A recent study proved that the average man lasts just 2-5 minutes in bed (during intercourse). The study also showed that many women need at least 7-10 minutes of intercourse to reach "The Big O" - and, worse still... 30% of women never get there during intercourse. Clearly, most men are NOT fulfilling there women's needs in bed. Now, as I've said many times - how long you can last is no guarantee of being a GREAT LOVER. But, not being able to last 20, 30 minutes or more, is definitely a sign that you're not going to "set your woman's world on fire" between the sheets. Question is: "What can you do to last longer?" Well, one of the best recommendations I can give you today is to read THIS report. In it, you'll discover a detailed guide to an Ancient Taoist Thrusting Technique that can help any man to last much longer in bed. I can vouch 100% for the technique because my husband has been using it for years :) Here�s the link to the report ■■■ https://tinyurl.com/rockhardxx

Cold Water Supply Distribution In Building

  1. 1. Prepared By: Heina Van Quimintan
  2. 2. Advantages:
  3. 3. Disadvantages:
  4. 4. Advantages: Disadvantages:
  5. 5. Operating Principle of an Air Pressure Water Distribution System “ Air is elastic or compressible and water is inelastic or noncompressible ” Thus, when air compressed into a closed compartment under atmospheric pressure to the extent of one half its volume content, the pressure will increase up to 15 pounds per square inch (psi). This pressure inside the tank is capable of elevating water up to 10.50 meters high.
  6. 6. The ideal air pressure range from 20 to 40 psi. By compressing the original pressure inside the tank is not enough. The slightest draw of water from the faucet substantially decrease the pressure and there is a possibility of water clogging inside the tank. To overcome this deficiency, an air compressor unit is installed so that the volume of air inside the tank will be increased to a pressure of one half the minimum required. An automatic pressure switch control that regulate the starting and the stopping of motor pump.
  7. 7. Advantages:  Eliminate the construction of a large house water tank.  low construction cost  Eliminate periodic cleaning of the tank Disadvantage: x dependent on electricity
  8. 8. DIRECT UPFEED SYSTEM- TRIPLEX PUMP Float switch House tank Roof 10 Floor 9 8 Upfeed 7 Upfeed 6 Down 5 4 3 2 1 Pressure Sensor Control Panel PU M PS Basement A. Constant Pressure Supply Control Panel PU M PS PUMPS Surge Tank B. Same as A with Surge Tank C. Conventional Roof Tank
  9. 9. The principle of operation is simple When the water demand is small, the small pump (jockey) will operate. As the water consumption increases to the point that the jockey pump could no longer cope with, the second larger pump starts automatically to replace the operation s of the jockey. As demand increases further to reach its peak, the third largest pump with full capacity to supply the entire building, will automatically operate to replace the second pump. Under this principle, only one pump operates at a time, depending upon the volume of water demand.
  10. 10.  Simultaneous draw or use of water  Height or distance to which the water must flow  Fluctuation of water pressure in the water main  Mineral elements in water that adhere to the interior of the pipe reducing the diameter  Inadequate size of the pipe
  11. 11. Maximum Demand refers to the maximum water discharge of fixtures in terms of fixture units. The maximum demand of water is equal to the Total Fixture Units in plumbing system, where one unit is valued at 8 gallons of water discharge per minute interval
  12. 12. Demand Weight of Fixtures in Fixture Units Private Public Fixture Group Fixture Units Water Closet 6 Lavatory 1 Fixture Group Fixture Units Water Closet 10 Pedestal Urinal 10 Bathtub 2 Stall/ Wall Urinal 5 Shower head 2 Lavatory 2 Bathroom group 8 Bathtub 4 2 Shower head 4 Separate shower Service sink (Office, etc.) 3 Kitchen sink 2 3 Kitchen sink (Hotel / Restaurant) 4 Laundry Tray 1-3 Combination Fixture 3
  13. 13. Example : Private Fixture Group Fixture Units Water Closet 6 Lavatory 1 Bathtub 2 Shower head 2 Bathroom group 8 Separate shower 2 Kitchen sink 2 Laundry Tray 1-3 3 Combination Fixture 3
  14. 14. Probable Demand One factor to be considered in determining the size of the water service pipe. The fewer the number of fixtures installed, the higher the percentage of probability of their simultaneous use, and the greater the number of fixtures installed, the lower the percentage of probable simultaneous use.
  15. 15. Number of Fixture Units Percentage of Simultaneous Use 1 to 5 6 to 50 51 or more 50 to 100 % 25 to 50 % 10 to 25 % Example
  16. 16. Find the number of fixture units then multiply by 8 19 units Multiply 19 units x 8 = 152 gallons Maximum demand Assume 30% reduction of 152 gallons. 152 x .30 = 45 gal. Subtract from maximum demand of 152 gallons 152 – 45 = 107 gallons Probable demand
  17. 17. used on small water distribution system for elevating water in wall or other sources Centrifugal Pump Tall building water distribution system Piston Pump Types of Pump
  18. 18. Centrifugal Pump Piston Pump (Double Acting)
  19. 19. Valve is necessary to avert serious damages of the installations in case of service breakdown. Types Of Valve  Gate Valve  Globe Valve  Angle Valve  Check Valve  Foot Valve  Safety Valve
  20. 20. Gate Valve
  21. 21. Gate Valve Two Types
  22. 22. Globe Valve It is a type of valve used for regulating flow in a pipeline consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. Three Types  Plug Type Disc Valve  Conventional Disc Valve  Composition Disc Valve
  23. 23. Globe Valve Has a wide bearing surfaces producing a good resistance to the cutting effect of scale, dirt.. etc Conventional Disc Valve Has a pressure tight bearing between the disc and the seat. It is recommended for cold and any temperature service. Composition Disc Valve Used for different services such as oil, gasoline, steam, hot or cold water
  24. 24. Check Valve prevent reversal of flow in the line. It is principally used in industrial pipings. It is classified into two types namely:  The swing check valve  The lift check valve
  25. 25. Swing Check Valve Vertical Check Valve Lift Check Valve Horizontal Check Valve
  26. 26. Angle Valve Operates in the same manner as the globe valve available in similar range of disc and seat design. It is used in making 90 degree turn in a line reducing the number of joints Foot Valve Located at the lower end of the pump and used mainly to prevent loss of priming of the pump
  27. 27. Safety Valve is used on water systems, heating systems, compressed air lines and other pipe lines with excessive pressure. Other Water Service Fittings and Devices      The corporation stop Curb stop Curb stop box Meter stop Water meter
  28. 28. Inserted into the water main. It serves as a control stop for the water service. It also serves as a shut off for disconnection of service Installed on the water service between the curb and the sidewalk line. Services : As a control stop, As a shut off in case the basement becomes flooded and As a control valve in case the building is not used on winter time.
  29. 29. Meter Stop serves as a controlling stop for the building installation Is a device used to measure the amount of water that passes through the water service.
