Problem 1 •

Consider a 210-MW steam power plant that operates on a simple ideal Rankine ccle! Steam enters the turbine at 10 MPa and "00#C and is cooled in the condenser at a pressure o$ 10 kPa! Show the ccle on a T-s dia%ram with respect to saturation lines& and determine 'a( the )ualit o$ the steam at the turbine e*it& ' b( the thermal e+cienc o$ the ccle& and ' c( the mass ,ow rate o$ the steam!

Problem 2  steam power plant operates on a simple ideal Rankine ccle between the pressure limits o$ . MPa and "0 kPa! /he temperature o$ the steam at the turbine inlet is .00#C& and the mass ,ow rate o$ steam throu%h the ccle is ." k%s! Show the ccle on a T-s dia%ram with respect to saturation lines& and determine ' a( the thermal e+cienc o$ the ccle and ' b( the net power output o$ the power plant!

Problem . Consider a 210-MW steam power plant that operates on a simple ideal Rankine ccle! Steam enters the turbine at 10 MPa and "00#C and is cooled in the condenser at a pressure o$ 10 kPa! Show the ccle on a /-s dia%ram with respect to saturation lines& and determine 'a( the )ualit o$ the steam at the turbine e*it& 'b( the thermal e+cienc o$ the ccle& and 'c( the mass ,ow rate o$ the steam!

Problem   steam power plant operates on a simple ideal Rankine ccle between the pressure limits o$ 12"0 and 2 psia! /he mass ,ow rate o$ steam throu%h the ccle is 7" lbms! /he moisture content o$ the steam at the turbine e*it is not to e*ceed 10 percent! Show the ccle on a /-s dia%ram with respect to saturation lines& and determine 'a( the minimum turbine inlet temperature& 'b( the rate o$ heat input in the boiler& and 'c( the thermal e+cienc o$ the ccle!
