The density of the liquid flowing through a horizontal pipe is 1200 kg/m3. the speed of the fluid at point a is 7.5 m/s while at point b it is 11 m/s. what is the difference in pressure, pb – pa, between points b and a? a. +5.0 × 104 pab. –1.9 × 103 pac. –2.5 × 104 pad. –3.9 × 104 pae. +3.8 × 103 pa

The difference in pressure between points B and A is

(D) is correct option.

Explanation:

Given that,

Density of the liquid = 1200 kg/m³

Speed of fluid at point A= 7.5 m/s

Speed of fluid at point B = 11 m/s

We need to calculate the difference in pressure between points B and A

Using formula of change in pressure

Where, = Speed of fluid at point A

= Speed of fluid at point B

D = Density of the liquid

Put the value into the formula

Hence, The difference in pressure between points B and A is
