Water flows in a horizontal constant area pipe;the pipe diameter is 75mm and the average flow speed is 5m/s. At the pipe inlet, the gauge pressure is 275kPa, and the outlet is at atmospheric pressure If the pipe is aligned so that the outlet is 15m above the inlet, what will the inlet pressure need to be to maintain the same flow rate

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
