1.Steam flows steadily through an adiabatic turbine. Theinlet conditions are 10 MPa, 450 C and 80 m/s. and the exitconditions are 10 kPa, 92% quality at 50 m/s. The mass flowrate of the steam is 12 kg/s. Determine the change in kineticenergy and the power output .Steam flows through an adiabatic air.
2.What are the units of specific heat? When undergoing agiven temperature change, which of these two common gasses -air or oxygen – experiences the largest change in its (a)enthalpy, and (b) internal energy.
Estimate the liquid volume of an aeration tank (units of m^-3) required to treat the following wastewater to a BOD effluent standard of 30.0 mg L^-1 and a suspended solids effluent standard of 30 mg L^-1.
Carbon dioxide at 30 C and 320 kPa absolute pressure expands isothermally to an absolute pressure of 170 kPa. Determine the final density of the gas.
A model of a submarine, at 1:15 scale, is to be tested at 0.8 ft/s in a wind tunnel at standard at mospheric pressure, while the prototype will be operated in seawater. Both the air and water are at 10 C (50 F).

A submerged stratum of clay has a thickness of 15m. The average water content of samples taken from the stratum is 54%, and the specific gravity of the solid constituents is 2.78.
A confined aquifer has a specific storage of 2.5 * 10^-6 /m . The porosity is .20 and the water compressibility is 5 * 10-10/Pa.For the aquifer skeleton compressibility you just calculated, what would the aquifer specific storage be if porosity were ..
For some minerals color is a diagnostic property making identification rather easy. However, certain minerals can also occur in a wide variety of colors making color a poor tool for identification. List different colors for the mineral quartz lo..
