(a) To determine The mass flow rate of the steam. Explanation Given: Inlet pressure of steam ( P 1 ) is 4 MPa . Inlet temperature of steam ( T 1 ) is 400 ° C . Inlet velocity of steam ( V 1 ) is 60 m / s . Inlet area of the nozzle ( A 1 ) is 50 cm 2 . Exit pressure of steam ( P 2 ) is 2 MPa . Exit temperature of steam ( T 2 ) is 300 ° C . Rate at which the heat is lost ( Q ˙ out ) is 75 kJ / s . Calculation: Refer Table A-6, “Superheated water”, obtain the inlet enthalpy and inlet specific volume of the steam at the temperature of 400 ° C and pressure of 4 MPa . h 1 = 3214.5 kJ / kg v 1 = 0.07343 m 3 / kg Refer Table A-6, “Superheated water”, obtain the exit enthalpy and exit specific volume of the steam at the temperature of 300 ° C and pressure of 2 MPa (b) To determine The exit velocity of the steam. (c) To determine The exit area of the nozzle.
