Explanation of Solution
Introduction:
The process of rapid cooling of a metal in water, or air or oil in order to alter the mechanical properties of the metal is called quenching. The process of quenching helps in the prevention of undesired low-temperature processes like phase transformation. Under normal conditions quenching is performed for few seconds.

- 6. A lake with no outlet is fed by a river with a constant flow of 1200 ft3/s. Water evaporates from the surface at a constant rate of 13 ft3/s per square mile of surface area. The surface area varies with the depth h (in feet) as A (square miles) = 4.5 + 5.5h. What is the equilibrium depth of the lake? Below what river discharge (volume flow rate) will the lake dry up?arrow_forwardProblem 5 (A, B, C and D are fixed).
