(1)Consider an air standard cycle in which the air enters the compressor at 1.0 bar and 20 degree celsius. The pressure of air leaving the compressor is 3.5 bar and the temperature at turbine inlet is 600 degree celsius.Determine per KG of air:
(i) Work availble at the shaft
(ii)Heat supplied to air
(iii) Efficiency of the cycle
(iv) Heat rejected in the coolant
(v)Temperature of air leaving the turbine.
(1) A gas turbine is supplied with gas at 5 bar and 1000K and expands it adiabatically to 1 bar. The mean specific heat at constant pressure and constant volume are 1.0425 Kj/kg K AND 0.7662 kj/kg K respectively.
(i) Draw the temperature-entropy diagram to represent the processess of the simple gas turbine system.
(ii) Calculate the power developed in KW PER kg of gas per second and the exhaust gas temperature.
When the outside temperature is -10°C, a residential heat pump must provide 3.5 x 106 kJ per day to a dwelling to maintain its temperature at 20°C. If electricity costs 8 cents per kWh, determine the minimum theoretical operating cost for each day of..
Determine the moments of inertia of the combined section with respect to its centroidal x and y axes.
A diesel engine is fitted with a turbocharger that comprises a radial flow compressor driven by a radial flow exhaust gas turbine. The gravimetric air-fuel ratio is 20:1; the air is drawn into the compressor at a pressure of 1 bar and at a temperatur..
determine the fourier coefficients a0 an bn and the trigonometric fourier series for the function yt at where the
A turbine uses steam at 25MPa and 650°C at the turbine inlet to generate 17.5MW of power. The steam enters the turbine at a rate of 90000kg/h. A portion of the steam passing through the turbine is removed for the purposes of feedwater heating (Figure..
As a game, slide a matchbook across a table, trying to make it stop at some predefined point on each attempt. Measure the distance from the starting point to the stopping point. Repeat this 10, 20, through 50 times. Plot the frequency distribution fr..
a differential thermocouple with sensors at the inlet and exit of a pump indicates that the temperature of water rises
two slender rods of negligible weight are pin-connected at a and attached to the 18-lb block b and the 80-lb block c as
a 4-in. diameter disk shown weighs 10 lb. the disk is released at rest when theta30 degrees and rolls down the curved
Methane (CH4) at 258C, enters the combustor of a simple open gas turbine power plant and burns completely with 400% of theoretical air entering the compressor at 258C, 1 atm. Products of combustion exit the turbine at 5778C, 1 atm.
