Question

Do not answer in scientific notation. Answer should be in decimal or in real number.

Water is the working fluid in an ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 1400
lbf/in.² and 1000°F and expands to 120 lbf/in.2, where some of the steam is extracted and diverted to the open feedwater heater
operating at 120 lbf/in.² The remaining steam expands through the second-stage turbine to the condenser pressure of 6 lbf/in.²
Saturated liquid exits the open feedwater heater at 120 lbf/in.² The net power output of the cycle is 5.5 x 108 Btu/h.
Determine for the cycle:
(a) the mass flow rate of steam entering the first stage of the turbine, in lb/h.
(b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator.
(c) the percent thermal efficiency.

Please do the last three questions (2, 3 and 4)! Thank you in advance! A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank.
