Solving for inlet pressure.

#### Inputs:

 pressure increase (P) pascal atmosphere bar dyne/centimeter^2 foot of water inch of mercury inch of water kilonewton/meter^2 millibar millimeter of mercury newton/meter^2 pound/foot^2 pound/inch^2 torr flow velocity (V) meter/second centimeter/hour centimeter/second foot/day foot/second inch/hour inch/second kilometer/hour kilometer/second knot mach sea level 15 C meter/day mile/hour mile/second millimeter/second speed of light in vacuum yard/second upstream pipe length (L) meter attometer centimeter chain dekameter decimeter exameter femtometer foot gigameter hectometer inch kilometer light year link megameter micrometer micron mile millimeter nanometer petameter picometer rod terameter yard valve closing time (t) second century day decade hour millisecond minute week year

#### Conversions:

 pressure increase (P) = 0 = 0 pound/inch^2 flow velocity (V) = 0 = 0 foot/second upstream pipe length (L) = 0 = 0 foot valve closing time (t) = 0 = 0 second

#### Solution:

 inlet pressure (Pi) = HAS NOT BEEN CALCULATED
