Two girls are balanced on a seesaw. If the girl on the left weighs 85 lb and is sitting 4.50 ft away from the fulcrum and the girl on the right weighs 95 lb, how far from the fulcrum should the girl on the right sit? Remeber: F1d1 = F2d2

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.
