If the intermediate and output shafts were to be 100 inch apart (still parallel), replace gears 3 and 4 with pulleys and find the right polyamide flat belt size (belt type and width) to achieve the desired torque and speed at the output shaft. Use a design factor of 1.1. The belt cannot be wider than 10 inches (if the designed belt width is larger than 10 inch, you can choose a stronger belt or change pulley diameters). Justify your design choices.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
