Q$.1$ Calculate the pipe size based on following data. Fluid flowing through pipe is carbon monoxide. Discharge pressure of carbon monoxide required from the pipe is atmospheric.

Available pressure at inlet of pipe $=75$kPag

Length of pipe $=6km$

Flow rate of $CO=2000k\frac{g}{h}$

Temperature of gas $=50C$

No$.$ of gate valves in pipeline $=2$

No$.$ of $45$ elbows $=5$

No$.$ of $90$ elbows $=7$

Viscosity of $CO=0\mathrm{.}010$mPa.s or $cP$

Consider the following pipe size for calculations
