A water is flowing through the duct having daimeter 15 cm and length 15 m. The inlet temperature of water is 100 °C & exit temperature is 5 °C respectively. Calculate the mass flow rate of water through the duct in mol/sec by considering heat transfer due to convection. Individual heat transfer coefficent is 15 w/m2K.
Water vapor enters a Lule with an input cross-sectional area of 0.02 m2 at a temperature of 1.8 MPa and 400C. Water vapor passes through the Lule with a flow of 5 kg/s, and in this process there is a heat loss of 2.8 kJ / kg from the Lule. If the pressure at the outlet is 1.4 MPa and the speed is 275 M/s, find the speed at which the water vapor enters the Lule and the temperature at the outlet of the Lule.
