Water Supply & DistributionQuestion 10 of 360
Estimating demand for a small apartment, you total the fixtures as: 8 lavatories (1 WSFU each), 6 water closets with flush tanks (2.5 WSFU each), and 4 showers (2 WSFU each). What is the total water supply fixture unit (WSFU) load?
a.23 WSFU
b.31 WSFU
c.46 WSFU
d.18 WSFU
Explanation
Lavatories = 8 x 1 = 8; water closets = 6 x 2.5 = 15; showers = 4 x 2 = 8; total = 8 + 15 + 8 = 31 WSFU. The other totals result from arithmetic errors such as omitting a fixture group or using incorrect unit values.
