The mass flow rate into a steam turbine is 1.5 kg/s, and the heat transfer from the turbine is 8.5kw. p1 =2 mpa p2=0.1 mpa . t1=350c v1= 50m/s v2=200m/s
find the power output of turbine

Which is not a step in the rock cycle?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
