Answer:
rate of makeup water added is 367.75 kg/s
Explanation:
given data
output power = 600 MW
efficiency = 36 %
waste heat = 15%
heat taken away in cooling tower = 85%
to find out
At what rate must 15ºC makeup water be provided from the river to offset the water lost in the cooling tower
solution
input power = ![\frac{power}{efficiency}](https://tex.z-dn.net/?f=%5Cfrac%7Bpower%7D%7Befficiency%7D)
input power = ![\frac{600}{0.36}](https://tex.z-dn.net/?f=%5Cfrac%7B600%7D%7B0.36%7D)
input power = 1666.67 MW
total heat = input - output
total heat = 1666.67 - 600
total heat = 1066.67 MW
and we know
15% of waste heat is released to atmosphere
so Q atm = 0.15 × 1066.667
Q atm = 160 MW
and
and 85% of heat is taken away in the cooling water so
Q cooling tower = 0.85 × 1066.667
Q cooling tower = 906.66 MW
so
we know at 15ºC from saturated water tables hfg will be
hfg = 2465.4 kJ/kg
so rate of water lost in cooling tower added by means of make up water that is
Q cooling tower = m × hfg
906.66 × 1000 = m × 2465.4
m = 367.75 kg/s
so rate of makeup water added is 367.75 kg/s
Answer:
1.4 mL
Explanation:
Given that:
volume of alcohol
= 500
Temperature change ΔT = (30° - 5°)C
=25° C
![\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C](https://tex.z-dn.net/?f=%5Cbeta_%7B%20alcohol%20%7D%3D%201.12%20%5Ctimes%2010%5E%7B-4%7D%20%2F%20%5E0C)
The increase in volume ΔV = ![\alpha \times V_o \times \Delta T](https://tex.z-dn.net/?f=%5Calpha%20%20%5Ctimes%20%20V_o%20%5Ctimes%20%5CDelta%20T)
![= 500 \times 1.12 \times 10^{-4} / ^0 C\times 25^0 C](https://tex.z-dn.net/?f=%3D%20500%20%5Ctimes%201.12%20%5Ctimes%2010%5E%7B-4%7D%20%2F%20%5E0%20C%5Ctimes%20%20%2025%5E0%20C)
= 1.4 mL
