Hi all, greetings from Indonesia again...
I need to calculate how much compressor power needed for this:

I need to cool 10.000 liter (roughly 2,641 gallon) of water from 30°C (86°F) down to 20°C (68°F) within one hour.

I found this formula:

BTU = gallons x temperature change x 8.33

The result for my numbers would be... 395,991 BTU or 155 HP.
Is that number seems realistic? It seems so high, or is there a mistake?

Thank you for all your input, really appreciate it.

Regards,
Yahya.
