Question

Liquid kerosene flows through a Venturi meter. The pressure of
the kerosene in the pipe supports columns of kerosene that
differ in height by 12 cm. Determine the difference in pressure
between points a and b, in kPa. Does the pressure increase or
decrease as the kerosene flows from point a to point b as the
pipe diameter decreases? The atmospheric pressure is 101 kPa, Kerosene
the specific volume of kerosene is 0.00122 m³/kg, and the
acceleration of gravity is g = 9.81 m/s².
v=0.00122 kg/m³
Pa 101 kPa
g=9.81 m/s²
L=12 cm

Expert Solution

Step 1

Introduction

In this problem, we will compute the pressure difference between points a and b by first calculating the pressure at limb a and pressure at limb b, and then calculating the pressure difference between points a and b while taking into account the atmospheric pressure effect.

Given data:

$\begin{array}{rcl} the difference of height (h) & = & 12 cm \\ the pressure at column A (P) & = & 101 kPa \\ the specific volume of kerosene (v) & = & 0.00122 m^{3} / kg \\ the acceleration due to gravity (g) & = & 9.81 m / s^{2} \end{array}$

Determine:

The difference in the pressure between point a and point b.
