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 andrv = 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 Ca)Calculate the surface temperature required to achieve the desired condensation rate of 0.09 kg/s( should be 688 degrees C) b) Show that if you use a bigger vertical plate (2.5 m-wide and 0.8 m-height), the requiredsurface temperature would be now 20 o C. You may use all the properties given as an initialguess. No need to iterate to correct for Tf. c) What if you still want to use small plates because of the space constrains? One way to getaround this problem is to use small…
