Answer:
The absolute pressure of air inside the tank is 164.7 psi.
Explanation:
Given that,
Atmospheric pressure = 14.7 Psi
Gauge pressure = 150 psi
We need to calculate the absolute pressure of air inside the tank
Using formula of absolute pressure

Where,
= gauge pressure
=atmospheric pressure
Put the value into the formula


Hence, The absolute pressure of air inside the tank is 164.7 psi.
Take wire and a nail strip 2 in of wire then wrap it around a nail
The pressure exerted by fluid at any given depth is exerted equally in all directions.
<h3><u>Explanation:</u></h3>
Pressure is defined as the force per unit area. Hydraulic force is the force that is exerted by liquid to a particle which is present somewhere inside the liquid. This pressure is exerted by the liquid particles from each part of the of the whole mass.
As far as the upper particles are concerned, the liquid exerts the force due to gravity, which acts downwards. Similarly, the particles which are down to the particle in liquid gives the reaction force which is based on Newton's third law of motion. This makes the force acts from all sides.
This is the reason why a particle which is submerged stays still, as there's no unbalanced force which can turn the particle.
