With two engines, we get a total of 10,821,300 x 2 = 21,642,600 cu-inches per minute of steam being supplied by the boilers. To get this in terms of cubic feet per minute we divide this result by 1728 cu-in per cu-ft. Therefore, the input steam supply rate is 21,642,600/1728 = 12,525 cu-ft per minute.
