You are conducting a wave equation analysis of piles (weap) for a single acting ape d30-32 diesel hammer. the contractor tells you that he would like to use three (3) layers of 1/2 inch thick micarta (em = 225 ksi) and five (5) layers of 5% inch thick aluminum (eal = 11,000 ksi) as the hammer cushion. these layers have a radius of 12.5 inches as they fit into the pile driving helmet. determine the elastic modulus of the composite hammer cushion. does it affect the composite modulus if he changes the order in which he places the aluminum and micarta layers together? briefly explain why or why not.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference

An air-conditioning system consists of a heating section and an evaporative cooler. air enters the heating section at 10°c and 70 percent relative humidity at a rate of 30m^3/min, and it leaves the evaporative cooler at 20°c and 60 percent relatively humidity. if the air conditioning system operates at a total pressure of 98 kpa, determine (a) the temperature and relative humidity of the air when it leaves the heating section, (b) the rate of heat transfer in the heating section, and (c) the rate of water added to air in the evaporative cooler
