A proposed closed system heat engine mimics the Carnot engine except that the heat rejection compressive process is not isothermal. The process has a 100 K change in temperature. The engine has 5 kg of air as the working fluid. Heat is supplied to the air at 1000 K and rejected by the air at an initial temperature of 500 K. The volume doubles during heat addition. At the end of compression, the pressure is 750 kPa. Assume the work is 900 kJ during the heat rejection process. Calculate the net cycle work in kJ assuming air is an ideal gas with constant specific heats.
Analysis of the motion of swing including velocity and acceleration plots of all moving parts and projectile analysis of projectile eg: flight path, horizontal distance, deceleration and launch velocity
Roll out a sheet of blu-tack, punch out a disk with your specified radius, assemble a flywheel for testing on an electric drill and determine the approximate critical rotation speed in rpm - SEM212 T1 2014
Solve this problem with a linear programming model. Describe the optimum mix of raw materials and production levels for the products. How much profit does the business make?
Tensile force formulas, A cylindrical steel beam is 2 inches diameter and 6 feet long. The modulus of elasticity is 30 x 1,000,000 psi. If the beam is subjected to a tensile force of 1000 lbs, what will be the resulting unit strain?
The explanation provided below, provide the solution to the problem in simple and easy to understand steps. A turbofan engine on a test stand in the maintenance shop is being run at a continuous setting of 22,700 lbs of thrust. The TSFC is 0.5 lbs/..
Assuming the plant operates on the ideal vapor-compression cycle using refrigerant 134-a between the pressure limits of 120 and 700 kPa, determine
Determine the stress in a stay at a given temperature. A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
To Verify the law for parallelogram of forces, law for triangle of forces and law of polygon of forces. These laws are very useful to calculate unknown forces in very short time.
A pitching wedge a golfer is using gives the ball a initial angle of 50 degrees, what range of velocities (Vo) will cause the ball to land within 3 ft of the hole?
An ideal vapor-compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf/in2, 20F, and saturated liquid leaves the condenser at 140 lbf/in2. The refriger..
Design Problem - Piston and Flywheel : Analyze the motion of the crankshaft AB and flywheel for 0 ≤ θ ≤ 4Π (two complete rotations of the crankshaft, or all four cycles, beginning and ending at TDC), for different values of the four design paramete..
Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.
