Homework Help: science/math

A juice processing operation uses steam to heat the fruit juice up to a temperature of 96̊C prior to packaging it in drink boxes. They need to heat 3,250 kg of apple juice (10.5% solids) from an initial storage temperature of 39̊F to its heat treatment temperature. How much saturated steam at 617.8 kPa would be needed for this task (to the nearest kg)? In this case, the condensate is to be discharged from the process without any further cooling to recover any of its heat and is returned to the “steam plant” where it is reheated and turned back into steam.

How much steam is required per batch of product (see description in Part a) if the condensate is discharged from the process after being cooled to 75̊C to use some of its heat in the process? Express your answer to the nearest kg

How much steam is saved by recovering some of the heat in the condensate (i.e., the difference between the process as outlined in part a as compared to the process in part b). Express your answer to the nearest of kg of steam.
