Alarge food processing plant requires 2 lbm/s or saturated or slightly superheated steam at 80 psi, which is extracted from the turbine of a cogeneration plant. the boiler generates steam at 1000 psi and 1000of at a rate of 5lbm/s, and the condenser pressure is 2 psi. steam leaves the process heater as a saturated liquid. it is then mixed with the feedwater at the same pressure and this mixture is pumped to the boiler pressure. assuming both the pumps and the turbine have isentropic efficiencies of 86 percent, determine a) the rate of heat transfer to the boiler and b) the power output of the cogeneration plant in kw.

During which interval are the persons represented by the graph not moving? a) 0 to 0.5 hrs b) 1.5 to 2 hrs c) 2 to 2.5 hrs d) 4.5 to 5 hrs

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.

Which change would make the diagram correct?
