an air-standard otto cycle uses 0.1 kg of air and has a clearance of 17%. THe intake conditions are 98 kPa and 37 C and the energy released during combustion is 1600 KJ/kg. What is the compression ratio of the cycle?
Plot the lift and drag forces exerted on an airfoil as a function of velocity. Use velocity values going from 0 to 45 m/s on a log-linear plot (log-scale on the y axis).
Create a CAD model of the planar robot
If the pipe is to be insulated with glass wool insulation (k=.05 W/m C) in order to decrease the temperature rise of water to .25 degrees C, determine the required thickness of the insulation.
What load P allow can be supported at the midpoint of the bar if the yield stress in the steel wires is 220 MPa and in the aluminium wire is 80 MPa? A saftey factor of n = 2 is needed.
The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 17 C, and 600 cm2
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
an ideal rankine cycle produces 100 MW of power. If the steam enters the turbine at 100 bar and 500C and is condensed at 1 bar, determine the flow rate of stream and the thermal efficiency.
A vapor-compression heat pump system uses R-134a as the working fluid. The refrigerant enters the compressor at 0.24 Mpa, 0 degrees Celsius, with a volumetric flow rate of 0.6m^3/min. The compression process is adiabatic to 0.9 MPa, 60 degrees Cel..
A piston-cylinder device has a volume of 0.1 cubic meters and contains 0.5kg of steam at 0.4 MPa. Heat is transferred to the steam until the temperature is 300 degrees Celsius
.How does data screening differ from data cleaning?
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
An ideal vapor-compression refrigeration cycle uses R-134a as the working fluid in an air-conditioning system. The refrigerant enters the compressor as a saturated vapor at 40 °F
