a 1m^3 tank is to be filled using nitrogen at 300K and 20MPa. Instead of using a valve to throttle the nitrogen in the tank, a reversible turbine is put in the line to get some work out of the pressure drop. if the pressure in the tank is initially zero, and the final pressure is 20MPa, what will be the final temperature in the tank? how much work will be accomplished over the course of the entire process?
Determine the natural frequencies of the system. For the baseline system I get natural frequencies at the following engine speeds: 435, 2026, 2818, 5225, 7093, 10245, and 12153 rpm.
Design a flat roof meeting certain mechanical performance criteria. The basic structure of the roof is a series of rectangular-section 'joists', made from softwood, that span the space to be covered by the roof.
Two infinite parallel plates are separated by a distance h. The space between them is filled with a Newtonian fluid: density (rho), viscosity (mu). The lower plate is fixed
A 20-mm diameter rod made of a ductile material with a yield strength of 350 MPa is subjected to torque of 100 N.m and a bending moment of 150 N.m. An axial force is then gradually applied. Determine the value of force when the rod begins to yield..
Calculating the heat transfer rate and the rate that entropy is produced in a gear box. A gearbox operating under steady state conditions recieves 24 hp along the input shaft and delivers 10hp along the output shaft

Determine Fourier Number, Compare two identical steel spheres, except the first has a two inch diameter while the second sphere has a four inch diameter. The larger sphere will have a Fourier number approximately
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
