5. The tank in Example 3.8 has a leak that admits air at the rate. 0.0005lbm (Poutside - Piank) min atm m How long does it take the pump to reduce the pressure in the tank from 1 atm to 0.01 atm? What is the steady-state pressure in the tank? Vacuum Sys 38

2C.4 Falling-cylinder viscometer (see Fig. 2C.4). A falling-cylinder viscometer consists of a long vertical cylindrical container (radius R), capped at both ends, with a solid cylindrical slug (ra- dius KR). The slug is equipped with fins so that its axis is coincident with that of the tube. One can observe the rate of descent of the slug in the cylindrical container when the lat- ter is filled with fluid. Find an equation that gives the viscosity of the fluid in terms of the ter- minal velocity of the slug and the various geometric quantities shown in the figure. Cylindrical slug descends- with speed t -XR- Cylindrical container filled with fluid Fig. 2C.4 A falling-cylinder viscom- eter with a tightly fitting solid cylin- der moving vertically. The cylinder is usually equipped with fins to maintain centering within the tube. The fluid completely fills the tube, and the top and bottom are closed.

If the level of the water h is constant, determine the exit velocity V2. If the water level h varies and V2 =8 m/s, find the rate change (dh/dt). Assume d=1m.

With the unique velocity profile of each liquid, determine the distance from the leading center to that point of the profile where the velocity is 3.2 m/s.
