Chapter 9, Problem 9.23P

Liquid water enters the boiler at 60 bar. Steam exits the boiler at 60 bar, 540°C and undergoes a throttling process to 40 bar before entering the turbine. Steam expands adiabatically through the turbine to 5 bar, 240°C, and then undergoes a throttling process to 1 bar before entering the condenser. Kinetic and potential energy effects can be ignored. Draw a Temperature-Entropy diagram and mark each of the states 2-5 on this diagram. Determine the power generated by the turbine, in kJ per kg of steam flowing. For the valves and the turbine, evaluate the rate of entropy production, each in kJ/K per kg of steam flowing.

A cast iron cylinder of 200 mm inner diameter and 12.5 mm thick is closely wound with a layer of 4 mm diameter steel wire under a tensile stress of 55 MN/m². Determine the stresses set up in the cylinder and steel wire if water under a pressure of 3 MN/m² is admitted in the cylinder. Take E= 100 GN/m², E = 200 GN/m² and Poisson's ratio = 0.25.

You are asked to design a unit to condense ammonia. The required condensation rate is 0.09kg/s. Saturated ammonia at 30 o C is passed over a vertical plate (10 cm high and 25 cm wide).The properties of ammonia at the saturation temperature of 30°C are hfg = 1144 ́10^3 J/kg andrho_v = 9.055 kg/m 3 . Use the properties of liquid ammonia at the film temperature of 20°C (Ts =10 o C):Pr = 1.463 rho_l= 610.2 kf/m^3 liquid viscosity= 1.519*10^-4 kg/ ms kinematic viscosity= 2.489*10^-7 m^2/s Cpl= 4745 J/kg C kl=0.4927 W/m C hfg*=hfg+0.68Cpl(Tsat-Given Ts) a) Instead of one plate you want to use small plates and install many of them. Calculate the requiredsurface temperature to achieve the desired condensation rate (0.09 kg/s) if you install 36vertical plates (with the same dimension as above: 10 cm high and 25 cm wide).
