Actually, there needs to be a few variables factored in to determine what size coil and what size pump is required.
Besides the dimensions of the coil these all factor in together... entering water temp at the coil,, flow rate of that water through the coil, the air cfm blowing through/across the coil to achive a desired air temp output [btu/hr].
The output changes as any one item changes.
Did I mention I like 3 speed pumps.
edit to add...c12 has added some good info.
