4. Superheated steam at 18 MPa, 560°C, enters the turbine of a vapor power plant. The pressure at the exit of the turbine is 0.06 bar, and saturated liquid leaves the condenser at 0.06 bar. The pressure is then increased by a pump to the boiler pressure at 18 MPa. The turbine and pump efficiencies are 82 and 77%, respectively. For the cycle, determine (a) The net-work per unit mass of steam flow, in kJ/kg (b) Heat transfer to steam passing through the boiler, in kJ/kg (c) The thermal efficiency of the cycle (d) Heat transfer to cooling water passing through the condenser, in kJ/kg. (e) Draw complete T-s diagram

Burning methane for the purpose of heating water toproduce steam in order to drive a turbine is an exampleof converting ___________ energy to ___________energy.

Steam enters the turbine of a steam power plant, operating on Rankine cycle, at 10 bar,300 C. The condenser pressure is 0.1 bar. Steam leaving the turbine is 90% dry. Calculate the adiabatic efficiency of the turbine and also the cycle η, neglecting pump work.

Attempt all three subparts. a proper explanation is a must

Get the following values for each stage: Stage 1: P1, T1, S1, H1 Stage 2: P2, T2, S2, H2 Explain how to get values please.

In a Rankine Cycle , saturated liquid water at 1 bar is compressed isentropically to 150 bar. First by heating in a boiler and then by superheating at constant pressure of 150 Bar, the water substance is brought to 750 K. After Adiabatic reversible expansion in a turbine at 1 Bar, it is then cooled in a condenser to a saturated liquid. What is the thermal efficiency of the cycle (%)?
