g ) Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Superheated vapor enters the turbine at 16 MPa, 560 oC, and the condenser pressure is 8 kPa. The cycle has a closed feedwater heater using extracted steam at 1 MPa. Condensate drains from the feedwater heater as saturated liquid at 1 MPa and is trapped into the condenser. The feedwater leaves the heater at 16 MPa and a temperature equal to the saturation temperature at 1 MPa. The mass flow rate of steam entering the first-stage turbine is 120 kg/s. Determine (a) the net power developed, in kW.

Answer:

146494 kw

Explanation:

Given data:

Turbine inlet pressure ( p1 ) = 16 MPa

Turbine inlet temperature ( T1 ) = 560°C

condenser pressure : P3 = 8Kpa

Extracted steam at pressure ( P2 ) = 1 MPa

mass flow rate of steam ( m ) = 120 kg/s

a) The net power developed

= 146494 kw

note: values of    h1, h2,  y, Wp   are all calculated values not included in the solution to make the solution less cumbersome.

PLZ HELP I GIVE BRAINLIEST!!

Consider a layer of insulation installed around a steam pipe. The radius of the pipe is R1 and the thickness of the insulation is R3-R1.The stream is maintained at a temperature TW and the air surrounding the insulation is at a temperature To and flows cross wise over the pipe. The air is flowed over the steam pipe at high enough velocity so a thermal boundary layer develops over the surface described by a heat transfer coefficient h.

Required:
Beginning with the heat equation, calculate the total quantity of heat being conducted per unit time (heat flow) through the insulation, Q (units: energy/time).
