This assignment is intended to give you practice at doing calculations in different unit systems.
Remember, use standard units, get standard units!
The following equation is known as Bernoulli's Equation. It relates the pressure, velocity, and
mass density of a fluid at different points in its flow.
v2

P

This equation means that, if you calculate the value at one point in the flow, it has the same
value at all other points in a connected flow. Another way to say this is
v2

In US units, the main challenge is that most quantities would not be given in standard units. If
v1 = 12 mph (not standard)
91 = 32.2 (standard)
Z1
O inches (not standard)
P = 16 psi (not standard)
lb
P1 = 8.354
gallon
I) Find the value of constant in the first equation, and its units. Do NOT convert to
metric. Convert to US standard units, and do the calculation using US units. Show your
process
2) If, at another spot in the flow, everything is the same except the flow velocity and z =
18 inches (not standard), determine the flow velocity at that point (in whatever unit
you like). Once again, do this calculation using US units.
