5) Steam is generated in the boiler of a cogeneration plant at 600 psia and 650°F at a rate of 34 lbm/s. The plant is to produce power while meeting the process steam requirements for a certain industrial application. One-third of the steam leaving the boiler is throttled to a pressure of 120 psia and is routed to the process heater. The rest of the steam is expanded in an isentropic turbine to a pressure of 120 psia and is also routed to the process heater. Steam leaves the process heater at 240°F. Neglect the pump work. Determine the rate of process heat supply. Use steam tables. The rate of process heat supply is Btu/s.

Concept explainers

Strain energy

The term strain indicates the variation in an object's length, area, and volume when the object is subjected to an external force. The external force may be of normal, shear, moment, torque, etc. The strain in an object depends on the types of external force and cross-section of the object. Mathematically, the evaluation of strain can be obtained with the help of elastic constants.

Please answer number 6. with complete solutions and box the final answer.
The attached answer was provided for the attached question. The equation uses the given temperature in celcius and the answer is also given in celcius. The temperature was used in the equation without converting from F and the answer was supposed to be in F. I am worried that even if I converted the answer to celcius that it would be correct because temperature was used in the equation using the incorrect unit.
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.
