How do you calculate satic pressure?
Consists of the pressure the air exerts in the direction of flow (Velocity Pressure) plus the pressure air exerts perpendicular to the plenum or container through which the air moves. (static pressure) In other words: PT = PV + PS PT = Total Pressure PV = Velocity Pressure PS = Static Pressure http://www.refrigeration-engineer.com/forums/archive/index.php/t-14342.html
What is the Difference between Dynamic pressure and static pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
What is static pressure in an Oahu?
for fresh air static pressure it shoul be high are low
Bernoullis principle about air velocity and pressure?
velocity and pressure have inverse relation. when velocity increases then pressure at that point decrease and vice versa.
Does static pressure affect flow rate?
Static pressure certainly does affect flow rate. Static pressure can slow or speed up flow rate based on the liquid.
What is stagnation pressure?
Static pressure is the pressure exerted by fluid in all directions, when it is in rest. Stagnation pressure is the sum of static and dynamic pressure of fluid in motion. Dynamic head is given by (velocity)^2/2*g.
Which friction slows down moving bodies kinetic or static?
Friction reduce the velocity, hence, it affect kinetic energy. The potential energy from static pressure is then drawn to maintain the velocity (transformation of potential -> kinetic energy). We then see the friction reduce the static pressure but actually, it affect kinetic first.

How do you prevent cavitation in pumps?
You have to increase the suction head, or decrease the speed of the pump. As you may know, cavitation happens when the static pressure at the pump inlet minus the equivalent pressure of the fluid velocity in the pump drops low enough to vaporize fluid. To prevent it, the static pressure needs to be higher or the velocity needs to be lower.
What is the relationship between pressure and airflow?
There are two types of atm pressure: static and dynamic. Static atm pressure stems solely from amount of air piled above the pressure point where the pressure is measured. We typically measure that at ground level; so the pressure is based on the weight of all the air above the ground. Dynamic air pressure is based in part on the static air pressure but as modified by the flow of the air above the pressure point where it's measured. A gent named Bernoulli found that the static air pressure is reduced by a predictable amount depending on air velocity when the air flows over the pressure point. And that's the answer. The static air pressure is reduced by air flow over the pressure point. In fact the amount of reduction is proportional to the velocity of the air flow over the pressure point.
What is the Difference between Dynamic pressure and static pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.

What is the result from investigating liquid pressure at a particular level?
If the liquid is static or moving with a constant velocity, then liquid pressure at a particular level is constant.In case the liquid is in accelerated motion we will get variation in the liquid pressure at a particular level
Is the pressure in a water main static?
No, it is not static

for fresh air static pressure it shoul be high are low
