Water at p1 = 20 bar, t1 = 400oc enters a turbine operating at steady state and exits at p2 = 1.5 bar, t2 = 240oc. the water mass flow rate is 4000 kg/hour. stray heat transfer and kinetic and potential energy effects are negligible. determine the power produced by the turbine, in kw, and the rate of entropy production in the turbine, in kw/k.

The softest and hardest minerals are: softest hardest

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
