Question

Водяной насос может создавать давление не более 220 кПа. На какую высоту он сможет подавать воду?

Answer 1

P=pgh
h=p/(рg)
h=220000/(1000*10)=22м

Answer 2

Water Pump Pressure and Water Height

A water pump with a maximum pressure of 220 kPa can push water to a certain height. The relationship between pressure and height in a water column can be calculated using the formula:

h = (P / ρg)

Where: - h is the height the water can be pushed to, - P is the pressure (220 kPa in this case), - ρ is the density of water, and - g is the acceleration due to gravity.

Using this formula, we can calculate the height to which the water can be pushed.

Calculation

Using the given pressure of 220 kPa and the density of water (approximately 1000 kg/m³), and considering the acceleration due to gravity (approximately 9.81 m/s²), we can calculate the height as follows:

h = (220,000 N/m²) / (1000 kg/m³ * 9.81 m/s²) h ≈ 22.42 meters

Therefore, a water pump with a maximum pressure of 220 kPa can push water to a height of approximately 22.42 meters.
