Design a single-cylinder atmospheric engine capable of lifting a mass of 1000 kg to a height of three meters. Assume reasonable values of cylinder temperature and pressure after combustion. Decide which direction the cylinder will move, and give the bore, piston travel distance, mass of piston, piston material, and clearance volume. Give a sketch of the mechanical linkage to lift the mass.
Calculate the total net thrust generated by the propeller. Calculate the propeller power used to generate thrust. The turbine driving the propeller generates 416 kW of power. Calculate the efficiency of the propeller.
Determine the speed at which the clutch starts to engage, the power transmitted at a speed of 1500 rpm.
nickel has a fcc crystal structure and 0.125 nm atomic radius. draw two nearest parallel 110 planes in a fcc crystal
Estimate average values of the fin heat transfer coefficients for free convection (hc) and radiation exchange (hr). Use these values to predict the tip temperature and fin effectiveness.
Aluminum fins of triangular profile are attached to a plane wall whose surface temperature is 250°C. The fin base thickness is 2 mm, and its length is 6 mm. The system is in ambient air at a temperature of 20°C, and the surface convection coeffici..
one kilogram of ammonia initially saturated vapor at -4degc undergoes a constant volume process to a final pressure of
The inner and outer surfaces of a 5 mm window glass are maintained at 10°C and 3°C. What is the amount of heat transfer through the glass in 5 hrs?
A piston-cylinder device contains 0.8kg of steam at 300 degrees C and 1 MPa. Steam is cooled at constant pressure until one-half of the mass condenses.
Determine the tube length required for the water vapor to reach 99% of saturation. What is the rate at which energy must be supplied to each tube to maintain its temperature at 298 K?
A rigid tank of 0.5 m^3 is filled with saturated liquid water at 300c. so if we open a valveat the bottom of the container and make the liquid is withdrawn from the container and if the temp is still constant but the the heat transferred to the water..
a wind turbine of the 3-bladed propeller type having 50 efficiency generates 2 mwe when the wind speed is 14 ms. the
