Water is pumped from a reservoir (water surface elevation = 111 m) and delivered to a higher elevation of 150.2 m as a free discharge through a 500 mm diameter pipe. the pump which is rated at 150 kw has a 70% efficiency. if the head loss in the pipe system is given by hl (m) = 46.42 q^2 (q in m^3/s). determine the discharge from the pump

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
