A steam power plant operates on an ideal reheat Rankine cycle between the pressure limits of 9MPa and 10kPa. The mass flow rate of steam through the cycle is 25kg/s. Steam enters both turbine stages at 500°C. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine:a) The pressure at which reheating takes placeb) The total rate of heat inputc) The thermal efficiency of the cycle.
Saturated water vapor at 200oC is isothermally condensed to a saturated liquid in a piston-cylinder device. Calculate the heat transfer and the work done during this process in kJ/kg.
consider 6.0 kg of austenite containing 0.45 wt c cooled to below 727 degrees celcius 1341 degrees farenheit.a what is

Using a centrifugal pump, and a flow rate of 60 gal/min, calculate the break hp of the pump using water with a density of 62.4lbm/ft3 and do the same for a nonviscous liquid having a density of 0.85g/cm3.
Consider a 70-kg woman who has a total foot imprint area of 400 cm2. She wishes to walk on the snow, but the snow cannot withstand pressures greater than 0.5 kPa. Determine the minimum size of the snow shoes needed.

A block of metal has a 90 notch cut from its lower surface. The notched part rests on a circular cylinder of diameter 2.0 cm, as shown in Fig. 4.15. If the lower surface of the par is 1.3 cm above the base plane, how deep is the notch?
assuming that the solid shaft has been replaced by a hollow shaft of the same cross-sectional area and with an inner diameter equal to half of its own outer diameter.
Calculate the steady state excess electron and hole concentrations as a function of distance into the semiconductor.
A full revolution press has 100 rpm flywheel rotation. The press is equipped with tow hand trip devices mounted on the machine at a distance of 20 inches from the point of operation. How many engagement points on the flywheel would be necessary to ma..
the frame ACD is supported by a ball-and-socket joint at A and D and by a cable which passes through a ring at B and is attached to hooks at G and H. Knowing that the frame supports at point C a load of magnitude P=268N, determine the tension in t..
Steam at 15 bar and 350 degrees C is expanded through a 50% reaction turbine to a pressure of 0.14 bar. The stage efficiency is 80% for each stage and the reheat factor is 1.05.
