A house has x meters of vertical piping with water flowing through. I'm just wondering if it is correct that one for every vertical meter of pipe loses 9,81 kPa of dynamic pressure?
Correct. Dynamic or static pressure.TSN79 said:A house has x meters of vertical piping with water flowing through. I'm just wondering if it is correct that one for every vertical meter of pipe loses 9,81 kPa of dynamic pressure?
Dynamic pressure is a measure of the force exerted by a fluid in motion. It is caused by the movement of the fluid and is calculated by multiplying the density of the fluid by the square of its velocity.
Dynamic pressure is one of the components of air resistance, also known as drag. As an object moves through a fluid, such as air, it experiences a force due to the fluid's resistance. This force is made up of two parts: static pressure and dynamic pressure. Dynamic pressure is the part of the force caused by the movement of the fluid.
This is due to the decrease in air density as altitude increases. As you move higher in the atmosphere, the air becomes less dense, meaning there are fewer air molecules per unit volume. This decrease in density results in a decrease in dynamic pressure, which is measured in units of kilopascals (kPa).
9,81 kPa is approximately equal to 1 atmosphere of pressure at sea level. This means that the dynamic pressure at sea level is equivalent to the pressure exerted by the entire weight of the Earth's atmosphere. As altitude increases, the dynamic pressure decreases due to the decrease in air density.
Dynamic pressure is an important factor in designing and analyzing objects that move through fluids, such as airplanes or cars. It helps engineers understand the forces acting on the object and how to optimize its design for maximum efficiency. In aerodynamics, dynamic pressure is often used in equations to calculate lift and drag forces on an aircraft.
