Mass Flow Rate Through 40 cm Tube at 18 m/s

In summary, mass flow rate is the measurement of the amount of mass that flows through a point in a system per unit time. It is calculated by multiplying the density of the fluid by the velocity and the cross-sectional area of the tube. The size of the tube can affect the mass flow rate as it determines the cross-sectional area, and the velocity of the fluid also has a direct impact on the mass flow rate. Other factors such as fluid viscosity, tube diameter, and obstructions can also affect the mass flow rate.

If I know air is flowing through a tube with diameter of 40 cm at 18 m/s, with P=1 atm, T=32 C how do I find the mass flow rate..thank you

Before we can help you, you need to show some of your own thoughts. If you are still unsure where to begin, see if you can find out what "mass flow rate" means and what variables are required to calculate it.

find surface area w/ 20cm radius, convert to Pa, multiply to get F, divide by velocity will give you kg/s
 

What is mass flow rate?

The mass flow rate is the amount of mass that flows through a given point in a system per unit time. It is typically measured in kilograms per second (kg/s) or other mass units per time unit.

How is mass flow rate calculated?

The mass flow rate can be calculated by multiplying the density of the fluid by the velocity and the cross-sectional area of the tube. In this case, the formula would be: mass flow rate = density * velocity * cross-sectional area.

What is the significance of a 40 cm tube in mass flow rate?

The size of the tube can affect the mass flow rate as it determines the cross-sectional area through which the fluid can flow. A larger tube would allow for a higher mass flow rate, while a smaller tube would restrict it.

How does the velocity of the fluid affect the mass flow rate?

The velocity of the fluid has a direct impact on the mass flow rate. A higher velocity means that the fluid is moving faster, resulting in a higher mass flow rate. In this case, a velocity of 18 m/s indicates a relatively fast flow of fluid.

What other factors can affect the mass flow rate through a tube?

Other factors that can affect mass flow rate include the viscosity of the fluid, the diameter of the tube, and the presence of any obstructions or bends in the tube. These factors can create resistance to the flow of fluid, which can affect the overall mass flow rate.
