The document discusses various concepts related to fluid dynamics including static pressure, dynamic pressure, and dynamic head. It defines static pressure as the pressure of non-moving fluid, while dynamic pressure is the pressure of moving fluid and equals the difference between total pressure and static pressure. Dynamic pressure is also defined as the kinetic energy within a unit volume of moving fluid particles. An equation for calculating dynamic wind pressure based on wind speed is provided. The document also notes that static and dynamic head are equal when the two surfaces of a liquid are at the same level, meaning they have the same head.

with the velocity of flow then
discuss them.
As we can see here on this plot ,with increasing of head of the static
fluid also the dynamic head of the fluid increases ,and vise versa also
as increasing ofthe dynamic movement of the fluid it makes its velocity
larger, this is due to the equation of dynamic include to find velocity
which is proportional to its velocity .
2-What is the difference between dynamic pressure and
static pressure?
Static pressure is the pressure of non-moving fluid or by another mean the
fluid is in equilibuirum, while the dynamic pressure is the pressure of the
fluid which they are in motion and not stable, vise versa of static fluids and
equals the diffrerence of total pressureand the static pressure .

2. 3-What is meant by dynamic pressure?
Dynamic pressure is the kinetic energy with in a unit of volume of the fluids
particles . and one of the terms of Bernoulli's equation is dynamic pressure
Also from the conservation of a fluids energy while its in motion we can
drive the equation of the dynamic pressure
4-How do you calculate dynamic wind pressure?
Wind pressure is given by the equation P = 0.00256 x V2, this is the
equation of the wind pressure while the V represents the speed of the wind
and its unit is in miles per hour (mph). but The unit for wind pressure is in
pounds over square foot (psf). For example, if a wind speed is 70 mph, we
can calculate its wind pressure and will equal to 0.00256 x 702 = 12.5 psf
using the equation of wind pressure .
5-When h(static) equals to h(dynamic)
This phenomemn happins in the appartues tube scale when the two surface
of the liquid are on same line by another mean they have the same head.the
two head can be more equal and precise
With increasing flow rate of the water this will make the ogyjin inside the
two valves to persave and spread in the two valves more equaly , but all
things happin if the valve above the liquid should be closed to
atmospheric(NOT OPEN).
