Equal in what way?
SCFH stands for Standard Cubic Feet per Hour, and it is a common unit of measurement for the flow rate of gases, such as air. It represents the volume of air (or gas) that flows through a system in one hour under standard conditions of temperature and pressure.
A helium balloon goes up because helium is lighter than the surrounding air, creating a buoyant force that lifts the balloon. This is due to the lower density of helium gas compared to the denser air around it, causing the balloon to float upwards.
10 mL of helium at standard conditions (STP) would weigh approximately 0.0125 grams.
Helium, hydrogen, and air are gases.
Helium has a lower density than air.
To convert 30,000 Standard Cubic Feet per Hour (SCFH) to inches of water (inH2O), you first need to know the specific gas density and the conversion factor. For air at standard conditions, 1 SCFH is approximately equal to 0.0085 inH2O. Therefore, you can multiply 30,000 SCFH by 0.0085 inH2O/SCFH to get approximately 255 inH2O.

SCFH stands for standard cubic feet per hour
"SCFH" stands for Standard Cubic Feet per Hour. This is a volumetric flow rate which is used for gases such as air. Since the volume of gases can change dramatically by pressure, a "Standard" is needed to bring the volume to a commonly known value (at sea level). The volume for liquids is typically incompressible and thus does not need a "standard" pressure when calculating volume or volumetric flow rates.
A helium balloon goes up because helium is lighter than the surrounding air, creating a buoyant force that lifts the balloon. This is due to the lower density of helium gas compared to the denser air around it, causing the balloon to float upwards.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
Because helium is lighter than air. An object in a fluid is buoyed up by a force equal to the weight of the displaced fluid. That's the reason that soap, logs, people, and boats float in water, and bags of hydrogen, hot air, or helium float in ordinary air.
10 mL of helium at standard conditions (STP) would weigh approximately 0.0125 grams.
Helium is lighter than air. so balloons filled with helium will float in air
Helium is lighter than air. So helium balloon rises in air.
a helium balloon is forced upward by buoyancy. a object is forced upward by a force equal to the weight of the fluid it displaces. this also applies to gases. the gas helium is lighter than average atmospheric air, that is that equal volumes of atmospheric air and helium do not weigh the same. This means that the volume displaced by the balloon is heavier than the balloon itself. since the air weighs more it applies more force upwards on the balloon than the balloon applies downwards on the air, therefore it rises. However, a helium balloon will not go down unless a force such as large air resistance (heavy wind etc.) is applied to it. hope this helps.
Any object surrounded by a fluid is buoyed up by a force equal to the weight of the fluid it displaces. There's an upward force on a cork in water that's equal to the weight of the water it displaces. There's an upward force on a helium balloon that's equal to the weight of the air it displaces. It so happens that a balloon full of helium weighs less than the air it displaces, so the upward force on it is greater than its weight.
