Answer:
Explanation:
The turbine at steady-state is modelled after the First Law of Thermodynamics:
The specific enthalpies at inlet and outlet are, respectively:
Inlet (Superheated Steam)
Outlet (Liquid-Vapor Mixture)
The power produced by the turbine is:
Given:
Temperature of water, = =273 +(-6) =267 K
Temperature surrounding refrigerator, = =273 + 21 =294 K
Specific heat given for water, = 4.19 KJ/kg/K
Specific heat given for ice, = 2.1 KJ/kg/K
Latent heat of fusion, = 335KJ/kg
Solution:
Coefficient of Performance (COP) for refrigerator is given by:
Max =
= = 9.89
Coefficient of Performance (COP) for heat pump is given by:
Max = = 10.89
It is called a ‘Waste Stream’
This should be right! Hope this helps, have a great day!
Answer:
A) 5 MPa , 55 MPa
B) maximum stress = 55 MPa, maximum shear stress = 25 MPa
Explanation:
using the given Data
free surface of a solid body
α = 50 MPa, α = 10 MPa , t = -15 MPa
