In an industrial process 10 kg of water per hour is to be heated from 20^@C to 80^@C . To do this steam at 150^@C is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at 90^@C . How many kilograms of steam is required per hour (specific heat of steam =1 cal//g^@C , Latent heat of vapourization =540 cal//g )?

Calculate the increase in the internal energy of 10 g of water when it is heated from 0^(0)C to 100^(0)C and converted into steam at 100 kPa. The density of steam =0.6 kg m^(-3) specific heat capacity of water =4200 J kg^(-1 ^(0)C^(-3) latent heat of vaporization of water =2.25xx10^(6) J kg^(-1)

Calculate the increase in the internal energy of 10 g of water when it is heated from 0^(0)C to 100^(0)C and converted into steam at 100 kPa . The density of steam =0.6 kg m^(-3) , specific heat capacity of water =4200 J//kgC ,latent heat of vaporization of water =2.25xx10^6 J kg^(-1)

Steam at 100^(@)C is added slowly to 1400 gm of water at 16^(@)C until the temperature of water is raised to 80^(@)C . The mass of steam required to do this is ( L_(V) = 540 cal/g)

A steam engin intakes 100g of steam at 100^(o)C per minute and cools it down to 20^(o)C . Calculate the heat rejected by the steam engine per minute. Latent heat of vaporization of steam =540 cal g^(-1) .

Water at 0^@C was heated until it started to boil and then until it all changed to steam. The time required to heat water from 0^@C to 100^@C is 5 min and the time to change boiling water to steam is 28 minutes. If the flame supplied heat at a constant rate, the specific latent heat of vaporization of water (neglecting heat losses, container etc. is (in J//g ). (specific heat of water s =4.2 J//g )

Heat required to raise the temperature of one gram of water through 1^@C is
