Apipeline 1200ft long and 8in. in diameter hasat its inlet point
75ft of available hydraulic energy with respectto the reference
level. the velocity in the pipe is 5fps; thepressure at its end is
12psi. the elevation at the end of the pipeis 10ft above reference
level. how much energy in horsepower islost by the water while
flowing through the pipe?

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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]
