Let the ends of a copper rod 100 cm long be maintained at 0 degrees celsius. suppose that the center of the bar is heated to over 100 degrees. celsius by an external heat source and that this situation is maintained until a steady state results. find the steady state temperature distribution. at t = 0 [after steady state part (a) has been reached], let the heat source be removed. at that the same instant let the end x= 0 be placed in thermal contact with a reservoir at 20 degree celsius, while the other end remains at 0 degree celsius. find the temperature as a function of time u (x, t).

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
