Q4) The nozzles receive steam at 1.75 MPa, 300 °C, and exit pressure of steam is 1.05
MPa. If there are 16 nozzles, find the cross-sectional area of the exit of each nozzle for a
total discharge to be 280 kg/min. Assume nozzle efficiency of 90%. If the steam has
velocity of 120 m/s at the entry to the nozzles, by how much would the discharge be
increased?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
