A water tank is constructed in the shape of a sphere seated atop a circular cylinder. If water is pumped into the tank at a constant rate, sketch a graph of the depth of water h(t) against time for the interval 0<t<c (10 points) A water tank is constructed in the shape of a s is pumped into the tank at a constant rate, sketch a graph of the depth of water h(t) against time for the interval 0 <...
A solution of water and dissolved salt enters a cylindrical vessel with radius R. The volumetric inlet flow rate of solution in the vessel is q1 and the concentration of salt in the inlet is c1. The solution inside the vessel is kept well-stirred (assume perfect and instantaneous mixing, and constant density of the mixture) and flows out of the tank with flow rate q2 (see Figure 1). Knowing that initially the vessel only contains pure water and that the...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
