Properties of Water

Question 1

Cp= kJ/ kg - °C
= Btu/ lb - °F

Answer 1

Cp= 4.187 kJ/ kg - °C
= 1.0 Btu/ lb - °F

Question 2

L= Latent heat of fusion = kJ/ kg
= Btu/ lb

Answer 2

L= Latent heat of fusion = 335 kJ/ kg
= 144 Btu/ lb

Question 3

Specific ( sensible ) heat of ice= kJ/ kg - °C
= Btu/ lb - °F

Answer 3

Specific ( sensible ) heat of ice= 2.093 kJ/ kg - °C
= 0.5 Btu/ lb - °F

Question 4

Latent heat of vaporization ( from and at 100 °C ) = kJ/ kg
= Btu/ lb

Answer 4

Latent heat of vaporization ( from and at 100 °C ) = 2257 kJ/ kg
= 970.3 Btu/ lb

Question 5

Latent heat of water vapor in air and flue gases ( average ) = kJ/ kg
= Btu/ lb

Answer 5

Latent heat of water vapor in air and flue gases ( average ) = 2442 kJ/ kg
= 1050 Btu/ lb
