A steam power cycle operates under the following conditions. Saturated water vapor enters the turbine at 10 bars (state 1) and leaves at 0.50 bar with a quality of 90.0 percent (state 2). The fluid leaves the condenser as wet mixture with 10.0 percent quality at 0.50 bar (state 3). State 4 (before boiler and after the pump) is a saturated liquid at 10 bars. Determine whether the cycle satisfies the Clausius inequality and sketch these processes in p-v diagram.

a coil spring is stretched by two equal and opposite forces f120n. the wire diameter is 5 mm and the mean coil diameter
for some transformation having kinetics that obey the avrami equation the parameter n is known to have a value of 1.1.
In the an ideal turbo jet, the engine is designed such that the turbine work is divided equally between the compressor and the propeller. The gas from the turbine discharges to a nozzle for additional thrust.
the motion of the slender 10kg rod AB is guided by collars of negligible mass that slide freely on the vertical and horizontal rods. knowing that the bar is released from rest when θ=30, determine the velocity of the collars A and B when θ = 60.
A water to water system is used to test the effects of changing tube length, baffle spacing, tube pitch, pitch layout and tube diameter. Cold water at 25C degree and 100,000 kg/hr is heated by hot water at 100 C degree; also at 100,000 kg/hr. the exc..
