Steam (h_f = 632.2, h_fg = 2113.2, h_g = 2745.4 kJ/kg) at 150°C is used to sterilize milk by direct steam injection. Milk is initially at 90°C and after sterilization, the blend of resultant milk and condensed steam (h_r = 567.6, h_fg = 2159.2, h_g = 2726.7 kJ/kg) are at 135°C. Specific heat capacity of milk is 3.8 kJ/kg K. Assuming no energy loss, the amount of milk in kg sterilized per kg steam supplied is
