The beam is constructed from two boards fastened together at the top and bottom with three rows of nails spaced every 4 in. a compound beam is formed by two stacked boards of width 9 inches and thickness 3 inches. the boards are joined by rows of nails at intervals of 4 inches, and v is downward through the thicknesses. each nail can support a 560-lb shear force

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.
