Technical Specs

Materials List:

All Drive Shower components are made from 316 Stainless Steel. The dimensions of
the tube are: .500 OD and .400 ID (.050 wall thickness), pick-up port hole dia. is .400

The mounting hardware consists of a 3/8 dia. X 16 (course  thread) hex headed SST

How much cooling water does your system supply?

The mathematical formula for the water volume for our dual pick-up system with a
.400 I.D. tube is:

Tube Capacity:

Pi (3.141593) x Rad(sq.) = 3.141593 x .200(sq.)
or 3.141593 x .04 = .125664
.125664 x 2 (2 pick-up ports) = .251327(sq. in.) tube dia. capacity

Water flow:

5280 ft./mi. or 5280*12  = 63,360(in/mi.) at 1 mph
63360(in./at 1 mi./hr.)  x .251327( = 15924( 1 mph)
15924( / 200  (qb. in./gal.) = 79.6(gals./hr.) at 1 mph

At  40 mph .  79.6(gals./hr.) x 40 = 3185 gal./hr. or 53 gals./min. or .9 gal./sec.

At 40 mph., the Multiport  Drive Shower® is supplying cooling water to the top half of
your drive at a rate that is approximately four times the flow of your bath tub
faucet. This is what it looks like
