The mass flow rate through a steam turbine operating under steady conditions is 100 kg/s. Steam enters the turbine at 12 MPa and 400oC. A mixture of vapour and liquid water exits the turbine at 10 kPa. At the exit state 93% of the mass of the water is in vapour form. The turbine loses heat to the surroundings at the rate of 3 MW. Kinetic and potential energy effects can be ignored.
Do the following:
a) Draw a schematic of the system and clearly indicate the system boundary using a dashed line. Indicate and label the mass flow inlets and outlets. Using arrows, illustrate the energy transfers between the system and surroundings by heat transfer and by work.
b) Write a 1st law energy balance for the system that agrees with your schematic. Cancel all unnecessary terms, providing justification for why these terms can be cancelled.
c) Draw the process on a T-s diagram, clearly indicating the state points and the isobars corresponding to the state points.
d) Calculate the power generated by the turbine in MW.
e) Calculate the change in specific entropy from inlet to exit in kJ/kgK.
Knowing that crank AB has a constant angular velocity of 160 rpm counterclockwise, determine the angular velocity of rod BD and the velocity of collar D when a. delta=0, b. delta = 90.
Consider a power plant operating on an ideal Rankine cycle without feed water heating. Steam enters the turbine saturated at 1000F at the rate of 5 x10 lbm/H. The turbine exhausts to a surface condenser at 1 psia. The condenser has an overall heat tr..

Air enters a compressor at 105 kPa and 300 K with a volumetric flow rate of 12 m3 /min and exits at 1200 kPa and 400 K. Heat transfer occurs at a rate of 2 kW from the compressor to its surroundings. Assuming ideal-gas behaviour for air, steady flow,..
A particle slides freely on a flat surface, attached to a mass less string that passes through a hole in the surface. At a given moment, the particle is moving in a circle of radius r0 with angular velocity w0. Assume that the string is pulled throug..
