pressure rating up to 40 mm will be 20 bars and higher sizes it will be reduced as PN-15.
250 bars
53 feet = 16.154 4 meterthe water pressure at 16.154 4 meters = 1.61544 bars + 1 bar of atmospheric pressure makes the absolute pressure = 2.62 bars.
Pressure is usually measures and calibrated in "bars".
Pressure is measured in PSI (pounds per square inch) or bars
1 bar is atmospheric pressure, or 15psi. 4 bar (not "bars") would therefore be 60psi.
15 million
720 Granola bars in 9 minutes720/9 = 80 Granola bars in one minute80 * 15 = 1200 Granola bars in fifteen minutes.
36 pound per square inches is equivalent to 2.48 bars (2.5 bars)
This is a stupid question
About 905 feet or 275m
Air pressure is measured in bar.
