The grade is a measure of quality and it captures concentration levels (i.e., how pure a certain fraction is). If grade captures
quality, then Recovery is a measure of quantity: it describes how much of certain material in the input stream is made available for reprocessing. A recovery of R% means that (100 - R)% of the material going into the process is lost, ending up either in mine tailings or as a contaminant in one or more fractions. By weight, copper wire contains about 70% copper and 30% PVC. Suppose we process 1 ton of wire per hour into a copper fraction of 0.74 ton/hour, of which 0.69 is copper and 0.05 is PVC. What is the weight and composition of the tailing?

Answer:
Check the explanation
Explanation:
To calculate weight when the mass is already known, make use of the formula weight = mass times gravitational acceleration. But kindly note that on the surface of the earth, gravitational acceleration is always 9.8 m/s^2, so simply plug in the mass and multiply it by 9.8 to get the weight in newtons.

Answer:
a) heat gain per unit tube length =
b) heat gain per unit tube length =
Explanation:
Assumptions:
- Constant properties
- Steady state conditions
- Negligible effect of radiation
- Negligible constant resistance between tube and insulation
- one dimensional radial conduction
a) What is the heat gain per unit tube length
Therefore
heat gain per unit tube length =
b) What is the heat gain per unit length if a 10-mm-thick layer of calcium silicate insulation (k_ins = 0.050 W/m.K) is applied to the tube
and
are the same, but
changes.
Therefore:
The total resistance
