A shaft design application for a conveyor belt system requires a mean time between service of 15000 hours, a desired reliability of 95% with an application factor determined to be 1.25, determine the required bearing catalogue rating if the design load is 375 lbs at 1800rpm. Assume the manufacture life rating is 90*10^6 with xo=0.02, θ=4.48 and b=1.49.

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.
