### PPT ON ORIFICE-METER.pptx

1. 1. KALI CHARAN NIGAM INSTITUTE OF TECHNOLOGY, BANDA LECTURE ON ORIFICE-METER FUNDAMENTAL OF MECHANICAL ENGINEERING (BME101) ( I SEMESTER ) BY : DEEPAK KUMAR YADAV ME DEPARTMENT
2. 2. ORIFICE-METER It is device used for measuring the rate of flow of a fluid through a pipe. It is a cheaper device as compared to venturimeter. It consists of a flat circular plate which has a circular sharp edged hole called orifice.
3. 3. RATE OF FLOW OR DISCHARGE THROUGH ORIFICE-METER • Let p1, p2 = pressure at section 1 &2 • v1, v2 = velocity at section 1 &2 • a1, a2 = area at section 1 &2 • Applying Bernoulli’s at section 1 and 2
4. 4. RATE OF FLOW OR DISCHARGE THROUGH ORIFICE-METER Or
5. 5. RATE OF FLOW OR DISCHARGE THROUGH ORIFICE-METER • Now section (2) is at the vena-contracta and a2 represents the area at the vena-contracta. If ao is the area of orifice then , we have
6. 6. RATE OF FLOW OR DISCHARGE THROUGH ORIFICE-METER Now Substituting this value of C c on Q , we get
7. 7. THANK YOU
