Trying to figure out how long a shower will last without running out of hot water.
I am using this calculator here
http://www.spiraxsarco.com/esc/Miscellaneous_Mixing_Water_Calculator.aspx?country_id=
Inputs are
Cold Water Temperature 50F
Hot Water Temperature 140F
Mixed Water Flow Temperature 105F
Mixed Water Flow Rate 2 US gal/min
It comes up with a hot to cold water ratio of 61%:39%
So I have a 50 gallon tankful of 140F water. I need to add 39% 50F water to it to get 105F
50gal x .39 = 19.4gal
50gal + 19.4gal = 69.4gal
68.4gal / 2 gal/min = 34.2 minutes worth of 105 shower water.
Is this correct?
