Water slide and spray gun heat loss calc

Water slide and spray gun heat loss calc

(OP)
I am designing the heating system for a recreation center in central Oregon and am wondering if anyone has any guidelines for determining heat loss for the 'play features' at the facility. The three items causing me the most concern are:
1. Water slide (outdoors)
2. A fountain feature in the kiddie pool (indoors)
3. A "spray pad" with a 270gpm spray feature and no standing water, water is collected into a below grade 1500 gallon tank, filter and reused in the spray. Not sure if this is just shooting up into the sky, or an aim-able gun or what. The pool designer has been more then a little difficult to get a hold of. (outdoors)

Obviously I will define all the details once I can talk with the pool designer, but I am still wondering how to estimate the heating load of these features. The only thing I can come up with is analyzing the spray features as an equivalent gpm cooling tower. My questions are:
a. Any more accurate/detailed calculation method?
b. What is a typical setpoint for the water in the spray?
c. Typ temp in a water slide? Same as pool, or can it be cooler?
d. Does just useing an activity factor (from ASHRAE calcs) of 1.5 for the associated pool cover the water slide? (This seems pretty clunky, there could be only a small catch basin or a 3000 sq. ft. pool at the bottom of the slide...

Thanks for any help.
