A flow process produces work using water as the working medium. The process is as follows: steam of quality 50% at 1 bar is compressed adiabatically to 20 bar; is heated isothermally by absorbing 3500 kJ/kg of heat; is expanded adiabatically to an unspecified final pressure; and is finally cooled isothermally until the steam returns to its initial state (steam of quality 50% at 1 bar). It is further reported that 53% of the heat added during the heating step is rejected during the cooling step. What is your evaluation of this process?

Compare MACRS depreciation and straight-line depreciation: based solely on the tax effects, which depreciation method (SL or MACRS) would yield a higher net present value for the project?
A typical feed stream composition is 55% ethylene, 5% inserts, and 40% water. A typical product stream is 52.26% ethylene, 5.49% ethanol, 0.16% ether, 36.81% water, and 5.28% inserts. Calculate the selectivity of ethylene for ethanol and for ether..

The problem statement, all variables and given/known data A tube scanner made of a PZT piezoceramic material, which has a piezoelectric coefficient, d31=- 0.27x10 -9 mV -1 , has a length of 12.5 mm and wall thickness of 0.5 mm.
For this assignment you will undertake an analysis based on a self-designed fictitious study that utilizes statistical analyses. You will first develop a fictitious problem to examine. It can be anything.
where V is the molar volume at temperature T, and a is a constant. Initially one mole of the gas is at temperature T1 and occupies volume V1. The gas is allowed to expand adiabatically into a vacuum so that it occupies a total volume V2.
n-Octane is compressed reversibly at constant temperature along the critical isotherm until the critical point is reached. The initial pressure is 1 bar. The pressure takes place in a closed system. Use the Lee-Kesler method to calculate what is t..
