In cryogenic equipment, cold gas flows in parallel over the surface of a 1-m × 1-m astm a240 410s stainless steel plate. the average convection heat transfer coefficient for the plate surface is correlated with the gas velocity as h = 6.5v0.8 , where h and v have the units w/m2⋅k and m/s, respectively. the temperature of the cold gas is −50°c. the minimum temperature suitable for the astm a240 410s plate is −30°c. to keep the plate’s temperature from going below −30°c, the plate is heated at a rate of 990 w. determine the maximum velocity that the gas can achieve without cooling the plate below the suitable temperature set by the asme code for process piping. the maximum velocity that the gas can achieve without cooling the plate below the suitable temperature is m/s.

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 in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
