4. A Diff. Pressure flow meter is calibrated to measure the flow of gas within 10 – 40 kg/min. the flow meter is designed to give 5 – 15 KPa differential pressure. And the meter 4-20 mA signal is designed to be linear with flow. (6)
a. Find the pressure difference and the current at 20kg/min flow?
b. Find the flow at 7 KPa pressure difference?

A venturimeter is used to measure water flow rate of 7.5m^3/min. If pressure difference between the wide and throat sections of the venturi is 12.50 kPa, and the pipe diameter at the wide section is 20 cm, calculate the throat diameter. (Use density=1000 kg/m^3 and coefficient of discharge Cd=0.96).

A venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at a speed v2 through a horizontal section of pipe whose cross-sectional area A2 = 0.0800 m2. The gas has a density of ρ = 1.70 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0500 m2 and has been substituted for a section of the larger pipe. The pressure difference between the sections is P2...
