Condensation of steam on a tilted plate. saturated steam at atmospheric pressure condenses on a 1 m x 1 m square plate that is tilted 30° from the vertical. the plate is maintained at 60°c by circulating cooling water through the other side. assuming laminar (wavy) conditions, determine
(a) the rate of heat transfer by condensation to the plate and
(b) the rate at which the condensate drips off the plate at the bottom.

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.
