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).

- A prismatic beam is built into a structure. You can consider the boundary conditions at A and B to be fixed supports. The beam was originally designed to withstand a triangular distributed load, however, the loading condition has been revised and can be approximated by a cosine function as shown in the figure below. You have been tasked with analysing the structure. As the beam is prismatic, you can assume that the bending rigidity (El) is constant. wwo cos 2L x A B Figure 3: Built in beam with a varying distributed load In order to do this, you will: a.

The pin acts as a moment release, i.e. no moments are transferred through this pinned connection. Shear forces can be transferred through the pinned connection.

A concentrated load, P, is applied to the mid span of beam CD, and acts at an angle as shown below.
