$2-52$E The pressure in a natural gas pipeline is measured

by the manometer shown in Fig. P$2-52$E with one of the

arms open to the atmosphere where the local atmospheric

pressure is $14\mathrm{.}2$ psia $.$ Determine the absolute pressure in the

pipeline.

$2-53$E Repeat Prob. $2-52$E by replacing air by oil with a

specific gravity of $0\mathrm{.}69.$
