Answer:
0.667 per day.
Explanation:
Our values here are

Degradation constant=k and is unknown.
We calculate the concentration through the formula,

Replacing values we have

That is the degradation constant of Z-contaminant
Answer:500,551.02
Explanation:
Given
Initial enthaly of pump \left ( h_1\right )=500KJ/kg
Final enthaly of pump \left ( h_2\right )=550KJ/kg
Final enthaly of pump when efficiency is 100%=
Now pump efficiency is 98%
=
0.98=

therefore initial and final enthalpy of pump for 100 % efficiency
initial=500KJ/kg
Final=551.02KJ/kg
Answer: Power
