the question gave point A is 40m higher than B ...Chestermiller said:
since 18.27 - 40 has negative value , so the water should flow from B to A ?Chestermiller said:
They probably meant to say that B is higher than A.foo9008 said:
Pressure difference is the difference in pressure between two points in a fluid or gas. It is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).
Pressure difference is calculated by subtracting the pressure at one point from the pressure at another point. The resulting value is the pressure difference between the two points.
Pressure difference is important in many scientific and engineering applications. It helps us understand fluid and gas behavior, and can be used to predict flow rates, forces, and other important parameters.
There are several factors that can affect pressure difference, including the properties of the fluid or gas (such as density and viscosity), the size and shape of the container or pipe, and the flow rate or velocity of the fluid or gas.
Pressure difference can be measured using various instruments, such as manometers, pressure gauges, and pressure transducers. These instruments can provide accurate and precise measurements of pressure difference in different types of systems.
