Consider a thin-walled, ﬁ xed-volume container of volume V that holds an ideal gas at constant temperature T. It can be shown by dimensional analysis that the number of particles striking the walls of the container per unit area per unit time is given by nv-/4, where as usual n is the particle number density. The container has a small hole of area A in its surface through which the gas can leak slowly. Assume that A is much less than the surface area of the container. (a) Assuming that the pressure inside the container is much greater than the outside pressure (so that no gas will leak from the outside back in), estimate the time it will take for the pressure inside to drop to half the initial value. Your answer should contain A, V, and the mean molecular speed v-.

An engineer proposes to decrease the gap between the windows of double pane window to decrease heat transfer. Is it good approach or not? O Yes, because by this way, less air will be trapped and therefore better insulation O Yes, because by this way, radiation heat transfer will decrease O Not sufficient information O No, because by this way, radiation heat transfer will increase O No, because by this way, current loops will be created inside the gap

Carbon steel (AISI 1010) shafts of 0.1 m diameter are heat treated in a gas-fired furnace whose gases are at 1200 K and provide a convection coefficient of 100 W/(m2*K).

Estimate the carbon steel’s properties at an intermediate stage’s temperature at 550 K. Show the equations of linear interpolation.B. Express the temperature equation of the shaft. Use the solution form of the lumped capacitance method, attached below. Evaluate the thermal time constant and substitute all available values in the equation.
