A heat exchanger is used to warm apple cider using steam as the heat source. The cider is heated from an initial temperature of 4 degrees celcius to a final temperature of 65 degree celcius. The steam enters the heat exchanger as 50% quality steam and exits as water condensate at 85 degrees celcius. Calculate the mass of steam required to heat 150 Kilograms of cider. (For the cider, assume the Cp = 3.651 KJ/Kg degrees celcius and latent heat = 280.18 KJ/Kg)
