Answer:
A. The flow diagram is in the attachment
B. Degree of freedom = 0
C. 0.486
D. Energy, power, cost of production
Explanation:
1/3 of water = 0.3333
Sugar = 1-1/3 = 2/3
B.) 45/55 = 9/11 when divided by 5
m1/m2 = 9/11
Cross multiply and make m1 subject of the formula
m1/m2 = 0.818
m1 = 0.818m2 ----1
0.15m1 + m2 = 1 x 0.667
0.15m1 + m2 = 0.667
0.15(0.818m2) = 0.667
1.1227m2 = 0.667
M2 = 0.5941
We put value of m2 in equation 1
M1 = 0.818 x 0.5941
M1 = 0.486
So 0.486 pound of strawberry is what we need in order to make 1 pound of jam.
D. We need great heat for water evaporation
The technical and economic factors would be
1. Energy which is power consumption
2. Cost of production for equipments and materials
3. Power
4. And hazards
