$1-67$E The pressure in a natural gas pipeline is measured by

the manometer shown in Fig. P$1-67$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.

$1-99$ The force generated by a spring is given by $F=kx,$ where

$k$ is the spring constant and $x$ is the deflection of the spring.

The spring of Fig. P$1-99$ has a spring constant of $8k\frac{N}{c}m.$

The pressures are $P_1=5000$kPa,$P_2=10,000$kPa, and

$P_3=1000$kPa. If the piston diameters are $D_1=8cm$ and

$D_2=3cm,$ how far will the spring be deflected? Answer: $1\mathrm{.}72$ cm
