Steam enters a well-insulated turbine at 500 bar and 600oC with a velocity of 100 m/s. The stream exits the turbine at 5 bar and 225oC with a velocity of 200 m/s. The turbine produces 32.5 MW of power. Calculate the steam mass flow rate (kg/s) through the turbine and the diameter (m) of the exit line assuming it is a cylindrical pipe.

What object a collides with object b and bounces back its final momentum is?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.

If we decrease the amount of force and keep all other factors the same what will happen to the amount of work
