Question 2 What is the maximum safe amount of refrigerant for a recovery cylinder with a water capacity of 50
lb, holding a refrigerant with a specific gravity of 0.9?
A. 50 lb x 0.9 = 45 lb
B. 50 lb x 0.8 = 40 lb
C. 50 lb x 0.8 x 0.9 = 36 lb
D. 50 lb

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
