Thermodynamics question

    • HOMEWORK PROBLEMS REQUIRE USE OF HOMEWORK TEMPLATE. THIS WAS ORIGINALLY POSTED IN WRONG FORUM.
    I have been struggling with this question for a while, please could somebody help?



    A pump is used to move water through a short pipe of diameter 120 mm as shown in Figure Q2. The water has a temperature of 18℃ and a pressure of 100 kPa (Absolute). The pump moves the water up a vertical distance of 3 m and the water exits to atmospheric pressure. Assuming the process is adiabatic and frictionless, and the required mass flow rate is 3.1 kg/s, determine, using the steady flow energy equation, the power required by the pump.

    thanks

    Have you written the steady flow energy equation for this system?
