You are engineering a feedwater system for a power plant and have decided to use a water tower. The plant must be supplied with 100 GPM at a pressure of 75 PSIG. If a 6- inch inner diameter commercial steel pipe is used as the supply line, what must the water tower height be? The very large reservoir at the top of the tower is at atmospheric pressure and 30 °C. The distance from the plant, L, is 1 km. Neglect minor losses

The higher the astm grain-size number, the coarser the grain is. 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]

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
