Steam at 4 MPa and 4008C enters a nozzle steadilywith a velocity of 60 m/s, and it leaves at 2 MPa and 3008C. The inlet area of the nozzle is 50 cm2, and heat is being lost at a rate of 75 kJ/s. Determine (a) the mass flow rate of thesteam, (b) the exit velocity of the steam, and(c) the exit area of the nozzle
