An air blower is to deliver 40,000 ft^3/min. Two U-tube gages measure suction and discharge pressures. The suction gauge reads a negative 2′′ of water. The discharge gage, located 3 ft above the point to which the suction gauge is attached, reads +3′′ of water. The discharge and suction ducts are of equal diameter. What size motor should be used to drive the blower if the overall efficiency is 68% (γ = 0.0750 lb/ft^3 for air)?
True or False: a.) For a mixing chamber, its conservation of mass principle requires that the sum of the incoming mass flow rate equal the volume mass rate of the outgoing mass. b.) The flow work is different for fluid pushed into and out of the control volume. c.) Cp is the sum of Cv and R d.) Mass flow rate can be expressed as mass equals density times velocity

Show the necessary figures if applicable 1.2 A pump, delivers 320 lps of oil (SG = 0.88), has a 400-mm diameter suction pipe and a 14-inch diameter discharge pipe. The suction vacuum gauge located 10 inches below the pump centerline reads 125 mm Hg. The discharge gauge, which is 20 inches above the pump centerline, reads 12 psi. Determine the pump power if the pump efficiency is 79 %. 1.3 A pipe discharges 142 lps of water into a reservoir at a point 1.85 m below the water surface. At point A the diameter is 25.4 cm and the center of the pipe is 1.25 m above the water surface. At the discharge end the pipe is 30.5 cm. If the head loss from A to the reservoir is 0.7 m, determine the pressure in A.

9.) The flow work relation (Wflow) is the same whether the fluid is pushed into or out of the control volume. Select one: True False 3.) For single stream devices like nozzles, the velocity usually become larger at the exit compared to the inlet that it also increases the pressure of the fluid flow. Select one: True False

Fluid Mechanics. Reg.no: 5395 Pb # 2: Water under a gage pressure of 65+(Reg.No/100) psi flows with a velocity of 12.5 fps through a right-angle bend that has a uniform diameter of (Reg.No/100) inches. The bend lies in a horizontal plane and water enters from the west and leaves towards the north. Assume no drop in pressure, what is the magnitude and direction of the resultant force on the bend.
