Q. 41 1.5 kg of water is in saturated liquid state at 2 bar (v = 0.001061 m/kg, Uf = 504.0 kJ/kg, h = 505 kJ/kg). Heat is added in a constant pressure process till the temperature of water reaches 400C (v= 1.5493 m/kg, u = 2967.0 kJ/kg h=3277.0 kJ/kg). The heat added (in kJ) in the process is Q. 42 Consider one dimensional steady state heat conduction across a wall (as shown in figure below) of thickness 30 mm and thermal conductivity 15 W/m.K. At x=0, a constant heat flux, q" = 1 105 W/m is applied. On the other side of the wall, heat is removed from the wall by convection with a fluid at 25C and heat transfer coefficient of 250 W/m.K. The temperature (in C), at x=0 is q" = 1105 W/m T x=0 T 2 T = 25C Q.43 number of the flow is Water flows through a pipe having an inner radius of 10 mm at the rate of 36 kg/hr at 25C. The viscosity of water at 25C is 0.001 kg/m.s. The Reynolds 0.001 kg/m.s. The Reynolds CO001 Q. 44 For a fully developed flow of water in a pipe having diameter 10 cm, velocity 0.1 m/s and kinematic viscosity 10-5 m/s, the value of Darcy friction factor is
