Reconsider Prob. 3–126. Using EES (or other) software, investigate the effect of rotational speed on the pressure difference between the center and the edge of the bottom surface of the cylinder. Let the rotational speed vary from 0 rpm to 500 rpm in increments of 50 rpm. Tabulate and plot your results.

Data from Problem 126.

A 1.2-m-diameter, 3-m-high sealed vertical cylinder is completely filled with gasoline whose density is 740 kg/m³. The tank is now rotated about its vertical axis at a rate of 70 rpm. Determine 

The difference between the pressures at the centers of the bottom and top surfaces 

The difference between the pressures at the center and the edge of the bottom surface.
