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(a) the difference between the pressures at the centers of the bottom and top surfaces and(b) the difference between the pressures at the center and the edge of the bottom surface.

Problem 113P

Solution 113 P

Step 1 :

In this question, we have cylindrical tank filled with gasoline, when this tank is rotated along vertical axis , we need to find difference in pressure at the centers of top and bottom of the tank

In the second part, we need to find difference in pressure at the center and edge of the bottom surface
