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.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
