400 Kilo Pascals... it is a measure of pressure.
800mm Hg Pressure and Volume are inversely proportional... thus is volume is halved (400ml -> 200ml) then pressure would double (400 mmHg -> 800 mmHg)
between 400 and 600 kpa
The pressure of 400 mmHg can be expressed as 53.33 KPa.
A : 845.46 kPa
The volume is 0,82 L.
Assuming ideal gas law, and closed system (constant volume) P1/T1=P2/T2, ensuring that the Temperature is in Kelvin so the new P is =854.5 kpa
13.78 kpa is.
Conversion for kPa to mmHG: kPa x 7.501 = mmHg202.6 kPa x 7.501 = about 1,520 mmHg
400 mL (Explanation): again boyle's law PV=PV. Since the pressure is halved (500 to 250), then the volume must be doubled in order to maintain this equation. 200 x2=400 so that's the answer
Depending where you live in the world, in South Africa, the average water pressure is between 400 to 600 kpa.
151.98 kPa is about 1.5 ATM
The absolute pressure is approximately 256 kPa.
