This article states that "the four RS-25 engines . . . . will burn their fuel at a rate that would drain one Olympic-sized swimming pool each second: that's 1,500 gallons." I have a 1500-gallon anhydrous ammonia tank not far from my house, and although it's a pretty good-sized tank, it is far, far smaller than the volume of water in an Olympic-sized swimming pool. I'd estimate that this statement is off by about a factor of 100.
