A mass of ice at -7 OC is needed to cool 114 kg of vegetables (Cp = 3.35 KJ /kg.K )in a bunker for 24 hours . The initial temperature of the vegetables is assumed to be 29 OC . It is also assumed that the average temperature in the bunker is 7OC within the 24 - hour period . If the heat gained per hour in the bunker is 25% of the heat removed to the vegetables from 30 OC to 8 OC, what would be the required mass of ice ?

A mass of ice at -7
OC is needed to cool 114 kg of vegetables (Cp = 3.35 KJ /kg.K )in
a bunker for 24 hours . The initial temperature of the vegetables is assumed to be 29
OC . It is also assumed that the average temperature in the bunker is 7OC within the 24 -
hour period . If the heat gained per hour in the bunker is 25% of the heat removed to the
vegetables from 30 OC to 8
OC, what would be the required mass of ice ?
