Consider a frictionless, massless and leak-proof plug blocking a rectangular hole of dimensions 2RL the bottom of an open tank as shown in the figure. The head of the plug has the shape of a semi-cylinder of r tank i The gravitational acceleration is g. Neglect the effect of the atmospheric pressure. The force F required to hold the plug in its position is The with a liquid of ensity up to the tip of the plug

Consider a parallel -flow heat exchanger with area Ap and a counter-flow heat exchanger with area Ac. In both the heat exchangers, the hot stream flowing at 1 kg/s cools from 80 C to 50 C. For the cold stream in both the heat ex the flow rate and the inlet The hot and cold streams in both the heat exchangers are of the same fluid. Also, both the heat exchangers have the same overall heat transfer coefficient. The ratiocpA/A is ers mperature are 2 kg/s and 10 c, respectively.
