The process data of a stream is as follows:

Gas flowrate $=285,000Sm\frac{3}{d},MW=30,$ visc $=0\mathrm{.}012cP,Z=0\mathrm{.}97$

Pressure $=700$kPag

Barometric pressure $=90$kPa

Temperature $=3C$

Find the pressure drop and the line sizing for the above gas stream, assuming$-$

Pipe straight length $=100m$

Pipe surface roughness factor $=0\mathrm{.}046mm$

$4$ long$-$radius elbows

$2$ fully open gate valves, disc type.

Start with Pipe ID of $154\mathrm{.}1mm(6$ NPS$,$ sch $40)$

Design criteria $10-20kp\frac{a}{100}m$ of Pipe length
