Note: • The pressure loss varies with the supplied pressure. Determine the pressure loss based
on the pressure curve(s) most near to the actual supplied pressure.
• The pressure loss of the natural gas can be obtained by multiplying the above pressure
loss by the specific gravity of natural gas, 0.64.
