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
bolt and spacer. The torque specification for the supplied bolt is 30 foot pounds.
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:
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
5280 ft./mi. or 5280*12 = 63,360(in/mi.) at 1 mph
63360(in./at 1 mi./hr.) x .251327(sq.in.) = 15924(qb.in./hr.at 1 mph)
15924(qb.in./hr.) / 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
