A steam power plant operates on a simple ideal Rankine cycle between the pressure limits of 3 MPa and 50 kPa. The temperature of the steam at the turbine inlet is 300 C and the mass flow rate of steam through the cycle is 35 kg/s. Show the cycle on a T-s diagram with respect to saturation lines and determine a) the thermal efficiency of the cycle and b) the net power output of the power plant.
He assumed that the blast wave radius R was a function of energy released E, air density , and time t. Use dimensional reasoning to show how wave radius must vary with time.
Determine the critical clearing time and critical clearing angle for the hydro and steam units using only the sin δ terms of the approximate transient torque-angle curve.
A duralumin tie bar of diameter 40 mm and length 600 mm carries a tensile load of 180 kN. If the bar contains a 30 mm diameter hole along 100 mm of its length, determine the
The components of the exhaust gas of a spark-ignition engine using a fuel mixture represented as C8H17 have a dry molar analysis of 8.7% CO2, 8.9% CO, 0.3% O2, 3.7% H2, 0.3
A mass transfer tower operating at 1 atm and 300 K uses water, which enters free of ammonia at the top, to reduce the ammonia (NH3) concentration in air exhausted from a react
Atmospheric air at a volumetric flow rate of 0.060 m3/s and 27°C is drawn through the sinks by a blower. Estimate the operating temperature of the board and the pressure dro
The top of a car has an area of 4 m2 and is at a temperature of 40 C. It’s speed is 40 mph. At what rate will it lose heat to surrounding air at 10 C if heat transfer coeffici
R-134a enters the condenser of a refrigerator at 800kPa and 50oC at a rate of 0.018kg/s and leaves at 800kPa as a saturated liquid. It is known that the compressor consumes 1.
