Water at 70 kPa flows through a horizontal 2 meter diameter pipe at a velocity of 71 m/s and an elevation of 54 meters. If the density of water is 1000 kg/m^3 and the specific weight is 9.8 kN/m^3, what is the total pressure? Round to the nearest kPa.

The total pressure is 3120 kilopascals.

Explanation:

The total pressure of this water flow is determined by the Bernoulli's Principle, which is the sum of dynamic () and hydraulic pressure (). That is:

Where:

- Density, measured in kilograms per cubic meter.

- Flow velocity, measured in meters per second.

- Specific weight, measured in newtons per cubic meter.

- Elevation, measured in meters.

- Static pressure, measured in pascals.

Given that , , , and , the total pressure is:

(1 kPa = 1000 Pa)

The total pressure is 3120 kilopascals.

the average speed is 24.57 km/hr

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
