6000 kg/h of steam at 10 bar and 4000C is expanded adiabatically to 0.5 bar in a turbine that generates power. The steam leaving the turbine is cooled by removing heat at the rate of 1.25 x 107kJ/h to produce saturated liquid at 0.5 bar. How much work is produced in the turbine (in kW)

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
