A gas turbine power plant produces a net power output of 100 MW with an overall thermal efficency of 35%
A) If the heating value of the natural gas fuel is 45000 kj/kg, determine the amount of the natural gas fuel burned in kg per day (24 hours).
B) If the air fuel ratio for the nautral gas combustion processis 17 kg air/kg fuel, determine the mass flow rate of air going through the burner in kg/s. If air is at 1 atm (101.3 kPa) and 300 K, what is the air volume flow rate in m^3/s?
water enters a turbine at 500oc and 6 mpa and leaves at 10 kpa what is the work output per unit mass if the turbine is
a car that weighs 3000 lb is traveling on a hill at a constant speed of 40.1 fps. the crest of the hill has a radius of
air enters a turbine operating at steady state at 500 kpa 860 k and exits at 100 kpa. a temperature is 460 k. stray
Refrigerant R-134a vapor in a piston-cylinder assembly undergoes a constant-pressure process from saturated vapor at 800 kPa to 50 ºC.
a pistoncylinder .5 kg steel altogether maintaining a constant pressure has .2 kg r134a as saturated vapor at 150 kpa.
Mechnical Vibration Analysis, How do I deduce the value of the viscous damping factor? How do I deduce the value of the viscous damping coefficient c?
A 50 hp motor with an efficiency of 0.80 is to be replaced by a newer model motor with an efficiency of 0.90. The motor is expected to operate 3000 hours per year. The cost of electricity in our area is $0.06 per kWhr.
question 1. a mild steel bar 40 mm diameter and 100 mm long is subjected to a tensile force along its axis.youngs
At a section in a passage, the pressure is 150 kPa (abs), the temperature is 10 deg C, and the speed is 120 m/s. For isentropic flow of air, determine the Mach number at the point where the pressure is 50 kPa (abs). Sketch the passage shape.
A vehicle of mass 1500kg and track 1.8m has a centre of mass located centrally at 1,1m above the ground. It has to travel around a bend of 56m radius to the centre of mass.
gas with an initial volume of 0.36 m3 is slowly compressed to a final volume of 0.16 m3 by a process during which the
A volume of 1.8 L of neon gas (monatomic) is at a pressure of 3.4 atmospheres and a temperature of 370 K. The atomic mass of neon is 20.2 g / mol. Calculate the mass of neon gas in SI units.
