Consider a steam power plant operating on the ideal Rankine cycle. Steam enters the turbine at 4 MPa and 300°C and is condensed in the condenser at a pressure of 10 kPa. Determine the effect of superheating and boiler pressure for following ranges; (i) steam temperature from 250 °C to 700°C (ii) Boiler pressure range 4 to 17 MPa (keeping turbine inlet temperature constant at 600°C).

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
