Steam is used for peeling potatoes in a semi$-$continuous operation. Steam is supplied at the rate of $4$ kg per $100$ kg of unpeeled potatoes. The unpeeled potatoes enter the system with a temperature of $17$ degree, and the peeled potatoes leave at $35$ degree C$.$ A waste stream from the system leaves at $60$ degree C$.$ The specific heats of unpeeled potatoes, waste stream, and peeled potatoes are $3\mathrm{.}7,4\mathrm{.}2,$ and $3\mathrm{.}5$ kJ$/($kg K$),$ respectively. If the heat content $($assuming $0$ degree C reference temperature$)$ of the steam is $2750$ kJ$/$kg$,$ determine the quantities of the waste stream and he peeled potatoes from the process.
