Please solve following problem. Especially I cannot understand how to get flow rate. A cylindrical drum of length l and radius r can rotate inside a fixed concentric cylindrical casing, theclearance space c between the drum and the casing being very small and filled with liquid of dynamicviscosity µ. To rotate the drum with angular velocity o requires the same power as to pump the liquidaxially through the clearance space while the drum is stationary, and the pressure difference between theends of the drum is p. The motion in both cases is laminar. Neglecting end effects, show that2µlro/3p =c2

The bottom quarter of a vertical cylindrical tank of total height 0.4 m and diameter 0.3 m is filled with a liquid (SG > 1, like glycerin) and the rest with water, as shown in the figure.

A receiver contains 0.25 m3 of air at a pressure of 1700 kPa and a temperature of 18 C. After a long period of time, the pressure is found to be the same as that of the atmosphere due to an extremely small leak. If the expansion is assumed to be isothermal, calculate the volume of air at the reduced pressure.
A cylindrical tank of radius 5 ft and height 9 ft is two-thirds filled with a liquid of weight density rho lbs./ft3. The work (in ft-lbs.) required to pump all the water over the upper rim is given by the integral
The solid- propellantrocket in Fig. P3.35 is self-contained and has no entrance ducts.Using a control volume analysis for the conditions shown inFig. P3.35, compute the rate of mass loss of the propellant,assuming that the exit gas has a molecular weight of 28.
The mass balance for a control volume can be defined as any change of masswithin the control volume is equal to the net gain of mass flowing into the volumethrough the control surface. Based on this definition, derive the equation of massbalance for 3 dimensional, unsteady and compressible fluid flows
