A 4-m-high and 6-m-long wall is constructed of twolarge 2-cm-thick steel plates (k 5 15 W/mK) separated by1-cm-thick and 20-cm wide steel bars placed 99 cm apart. Theremaining space between the steel plates is filled with fiber-glass insulation (k 5 0.035 W/mK). If the temperature dif-ference between the inner and the outer surfaces of the wallsis 22C, determine the

A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance of the turbine the temperature is 450 deg C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water in the condenser is subcooled by 6.3 degC. The boiler is sized for a mass flow rate of 20 kg/s. Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.

Steam flows through a copper pipe (kc=150WmK) that has an inner diameter of 19 mm and an outer diameter of 21 mm. The convection coefficient between the 200C steam and the pipe is 200Wm2K. The pipe is wrapped with insulation (ki=0.03WmK) so that the outer surface of the insulation is safe to touch. If the inner surface of the pipe is at 180C: a) What is the temperature of the outer surface of the pipe for unit length of the pipe (or the inner surface of the insulation)? b) What is the thickness of the insulation so that the temperature is 40C at the outer surface of the insulation? (Note: Assume negligible contact resistance)

In order to properly construct this road you have determined that you need to bring in 135,000 CCY of fill material to construct the sub-base. The fill material that is available is dry earth, with a weight of 2800 lbs/BCY and a moisture content of 7%. The percent swell for this soil is 25%. The final compaction level will be 118 PCF dry density and the optimum moisture content is 6%. How many BCY of earth must be excavated to meet this requirement
