Horizontal Reach of a Solid Hose Stream
S =
√(HF)√(P)
S = distance
HF = horizontal factor
P = nozzle pressure
Values of Horizontal
Factors (note: base is 1/2''tip and factor 56,than there is a increase
of 6 for each 1/8'' in tip size)

Horizontal Reach of a Solid Hose Stream (second formula)
This formula is useful for tip sizes of 3/4'' and bigger
with Nozzle Pressure (NP) over 30 PSI.(NOTE: For nozzle tips bigger than 3/4''
you MUST add 5 to the 26 for EACH 1/8'' increase in tip size)
S = 1/2 P + 26
(note: add 5 for each 1/8'' increase in tip size)
Velocity Flow
V = 8
√H
(when head is known)
V = velocity flow in
feet per second
H = head
V = 12.14
√P (when pressure is
known)
Comparing the velocity flow in the hose with the velocity flow at the nozzle
tip
VD²
= vd²
V = velocity flow trough
the hose
D = diameter of the hose
v = velocity flow from
the nozzle tip
d = tip size
