Answer:
1 13/64
Explanation:
The depth of the hole is the height of the block less the remaining material below the hole:
depth = 1 3/8 +1 15/16 - 3/8 = (1 3/8 -3/8) +1 15/16 = 2 15/16
We want to find the difference between this depth and the depth of the hole already drilled:
2 15/16 -1 47/64 = 2 60/64 -1 47/64
= (2 -1) +(60 -47)/64 = 1 13/64
The hole must be drilled 1 13/64 deeper to match the drawing.
Answer:
Net Power output 144 GJ/h
Explanation:
Given data:
Heat received = 300 GJ/h
Heat lost 
Heat to the water 
Net Power output 
= 300 - 16 - 140
= 144 GJ/h
thermal efficiency
= 0.514 = 51.41 %
The basic scheme of a product life cycle includes the three phases production, use and end of life. In the production phase, raw materials are transformed into the product. In the use phase, the product delivers the service it has been intended for.
Explanation:
Answer:
Evaluate the required thickness of styrofoam for the freezer compartment in the previous problem when the inside wall is exposed to air at -10°C through a surface coefficient of 16 W/m2 · K and the outer wall is exposed to 33°C air with a surface coefficient of 32 W/m2 · K. Determine the surface temperatures for this situation.
