Is this normal evaporation?

I evaporate this much a day;. And today has been unusual a lot of evaporation my system is 150G. My basement is not heated. It sits at 66F 40% humidity. Is that why?

looks normal to me. My 180 uses about 1.2 gal/day.

Looks normal.
My 150 uses 1.75g's a day.

I lose about 1 gallon per day in my 150, so it’s normal.

With low humidity, the dry air will increase evaporation. When water evaporates, 1000BTU’s per pound of water evaporated cools both air & water.

When I operated 10KG of Maraculture in 20’ by 40’ greenhouse, during Texas summer, I made up for evaporation between 100-150 GPD to maintain water < 80 degrees F. That is > one million btu of cooling per day.

Is 40% considered low humidity for my basement?

I have no idea where you live or what your normal humidity is.

Here in Austin, Tx I run air conditioning to keep humidity below 60%.

Also, in the humid South, 70% of air conditioning heat load is moisture in the air.

In the winter, I run humidifiers to keep room < 60%

Here it would be considered low in summer, but about average in winter.
