A column carries a load of 20,000 lbs and is supported on a 2 foot thick, concrete spread footing which rests on clay. Size the smallest round footing that can support the load. Enter the diameter of the smallest footing possible. (round only the final answer to the tenths and do not include the unit).

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
