Using conservation of mass:
mass flow rate = ρ * V * A
where ρ= density, V= velocity, and A= cross sectional area
therefore since massin = massout
therefore:
(ρ*V*A)in = (ρ*V*A)out
To calculate the flue gas velocity in an air preheater, you would need to know the volumetric flow rate of the flue gas passing through the preheater and the cross-sectional area of the preheater. You can then use the formula: Velocity = Volumetric flow rate / Cross-sectional area of preheater. This calculation will give you the velocity at which the flue gas is moving through the air preheater.
This is the ratio volume/time.
Equipment such as graduated cylinders, measuring beakers, electronic balance, and flow meters can be used to measure the volume of water accurately. Graduated cylinders and measuring beakers are common tools for measuring liquid volumes, while an electronic balance can be used to measure the weight of water to calculate volume. Flow meters can also be used to measure water volume as it flows through a pipe or a channel.
You can compare the flow rates of liquids by measuring the volume of liquid that passes through a specific point in a given amount of time. This can be done using a graduated cylinder, flow meter, or by measuring the time it takes to fill a container of known volume. Comparing these measurements will allow you to determine which liquid has a faster flow rate.
The time it takes to flow 300 gallons through a 1 inch pipe at 55 psi depends on the flow rate of the pipe. You would need to know the flow rate in gallons per minute (GPM) of the 1 inch pipe to calculate the time it takes. Without the flow rate, it is not possible to determine the exact time it will take.
The pipe flow formula used to calculate the flow rate of a fluid through a pipe is Q A V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
The duration a size H cylinder of heliox will last depends on the flow rate it is used at. For example, if the flow rate is 4 liters per minute, a size H cylinder typically lasts around 4.5 hours. You can calculate the estimated duration by dividing the cylinder's capacity (in liters) by the flow rate (in liters per minute).

To calculate the duration of oxygen flow from an E-cylinder, you can use the formula: (Cylinder pressure in psi x Cylinder factor) / (Flow rate in L/min x 1.8). For a 4.5-liter cylinder at 2000 psi with a flow rate of 5 liters per minute, and a cylinder factor of 0.16, it would take approximately 142 minutes to empty the cylinder.
The pipe velocity equation used to calculate the flow rate of a fluid through a pipe is Q A V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
Refrigerant pressure in a graduated cylinder is maintained by adjusting the flow of the refrigerant entering the cylinder. A valve connected to the cylinder regulates the flow of refrigerant, allowing the pressure inside the cylinder to be controlled. Monitoring and adjusting the valve ensures that the desired pressure level is maintained during the experiment.
A funnel typically has a conical shape with a wide opening at the top and a narrow spout at the bottom. It is used to channel liquids or powders into a container with precision and minimal spillage by guiding the flow through its tapered design.

To calculate pressure from flow rate, you can use the formula: Pressure Flow Rate x Resistance. The resistance is typically represented by the diameter and length of the pipe through which the fluid is flowing. By knowing the flow rate and resistance, you can determine the pressure of the fluid in the system.
The duration a J size oxygen cylinder will last depends on the flow rate at which the oxygen is being accessed. To calculate this, you need to divide the cylinder's capacity (in liters) by the flow rate (in liters per minute) to determine the approximate duration in minutes. For a more accurate estimation, consult with a medical professional or oxygen provider.
