Answer:
final pressure = 0.7 MPa
quality = 20 degree super heat.
Explanation:
Given data:
water temperature 120 degree celcius
quality
we know that from saturated water temperature table . for T =120 DEGREE
we know that
= 0.001060 + 0.33(0.89133- 0.001060)
= 0.29485 m^3/kg
frinal temperature of water is
= 120 + 65 = 185 Degree
from saturated water temp. table
for T = 185 degree, VG = 0.17390 m^3/kg
from super heated table by interpolation
final pressure = 0.7 MPa
quality = 20 degree super heat.
Answer:
option C
option A
Explanation:
Enthalpy gained by air= 1023-290
= 733 kJ/kg
Rate of energy gain= mass flow rate × Enthalpy gained by air
= 0.1 × 733
= 73.3 kJ/s
rate of heat transfer between compressor and air= 77kW
Heat loss by air to surroundings= 77-73.3
=3.7kW
Enthalpy lost by steam in turbine= 1407.6-1236.4
= 171.2 Btu/lb
Rate of energy transfer to turbine= Enthalpy lost by steam× mass flow rate
= 171.2×5
= 856 Btu/s
Net rate of energy transfer to turbine=rate of Energy transfer to turbine- rate of heat transfer to turbine
= 856-40
= 816 Btu/s
Explanation:
The end-use industries of thermochromic materials include packaging, printing & coating, medical, textile, industrial, and others. Printing & coating is the fastest-growing end-use industry of thermochromic materials owing to a significant increase in the demand for thermal paper for POS systems. The use of thermochromic materials is gaining momentum for interactive packaging that encourages consumers to take a product off the shelf and use it.
Answer:
Divide the difference in tax by the amount of income from the investment, and you'll get the economic marginal tax rate from investing. Most people refer to marginal tax rates as being identical to tax brackets.
hope this helps
have a good day :)
