Question

(Based on text problem 1.21) A cook weighing 200 lbm brings 100 apples (0.5 lbm each) into the kitchen, stores 36 of the apples in the refrigerator, and puts the rest on table to make applesauce. While the cook is mashing the apples into sauce, three young friends (70 lbm each) enter the kitchen. The cook gives them 6 apples each from the table, and they take them outdoors. After finishing the sauce the cook leaves the kitchen. Considering the kitchen as a control volume (open system), A) Draw the control volume and show inflow and outflow of mass (consider both apples and human beings as substances). (10) B) Complete the following table. (30) Quantity (units) || Mass (lbm) || Apples (#) || Sauce (lbm) Inflow || || || Produced || || || Outflow || || || Stored || || || Destroyed || || ||

Explanation / Answer

weight of cook w = 200 lbm weight of 100 apples w1 = 100 * 0.5 lbm = 50 lbm weight of three young friends w2 = 3 * 70 lbm = 210 lbm inflow of mass W = w - w1 outflow of mass W1 = w1 + w2 Sauce inflow W2 = 64 * 0.5 lbm outflow of mass W3 = 36 * 0.5 lbm
