Power requirement for pumping a compressible flow fluid through a long pipe

Input(s)

D: Diameter of Pipe (ft)

ρ1\rho_{1}: Pressure (psi)

M: Mass (lbs)

R\mathrm{R}: Constant (ft3psi/lbmolK)\left(\mathrm{ft}^{3} \mathrm{psi} / \mathrm{lbmol} \mathrm{K}\right)

T\mathrm{T}: Temperature (K)(\mathrm{K})

Wm: Energy Required by Compressor (ft lbf/lbm)

v\mathrm{v}: Velocity (ft/s)

Output(s)

P: Power (hp)

Formula(s)

P=(v1)π(D2)ρ1MWm4R T\mathrm{P}=\frac{\left(\mathrm{v}_{1}\right) * \pi *\left(\mathrm{D}^{2}\right) * \rho_{1} * \mathrm{M} * \mathrm{Wm}}{4 * \mathrm{R} * \mathrm{~T}}
