Water is flowing through a venturimeter shown. The difference in pressure between points 1 (D = 5cm) and point 2 (D = 2cm) is measured using open tubes. If h is 60cm, solve the velocity head at point 1 in meters. Use g = 9.81m/s^2. %3D %3D %3D Note: Do not include units in your answers. Do not round off intermediate values and answer in four decimal places.

Completely solve and box the final answers. Write legibly 9. A blower with the inlet open to the atmosphere delivers 250 cubic meters per minute of air at a pressure of 2.50 cm of water gage through a duct 25 cm in diameter, the manometer being attached to the discharge duct at the blower. Air temperature is 25 degrees C and the barometer pressure reads 1.025 bar. Calculate the required motor rating in KW if the blower efficiency is 92.5%

Compute the pressure difference between m and n, in pounds per square inch, when: a) Fluid A is brine (sp gr 1.15), the gage fluid is oil (sp gr 0.92), and z = 49.69 in.b) Fluid A is water, the gage fluid is air, and z = 19.69 in.
