Compute the number of kilograms of hydrogen that pass per hour through a 5-mm thick sheet of palladium having an area of 0.4 m2 at 500°C. Assume a diffusion coefficient of 1 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
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..
The polynomial method is to be used to solve the equation. For the graphs, Mathcad or similar program is necessary to graph the solution.
Volumetric Compression Ration and Mean Effective Pressure of a Diesel Engine, A diesel engine has air before compression at 280 K and 85 Kpa. The highest temperature is 2219 K and the highest pressure is 6 MPa.
A process with Gp= 2/(2s+1) and Gd=1/(2s+1) experiences a disturbance step change of magnitude 5. The SP remains constant. If a P-controller alone with Kc=1 is used and Ga=Gs=1, then what is the output variable, delta Y(t) versus time?
Use steam tables to compute the total volume, total enthalpy, and total entropy of 1kg of water at 100o C, half by weight of which is steam and the remainder is liquid water.
