Find c2 with mf and v - Step by Step Explanation

  • Thread starter engrme
  • Start date
In summary, to find c2 with mf and v, you can use the formula c2 = mf x v. This represents the product of the mass flow rate (mf) and velocity (v). Finding c2 is important as it represents the speed of sound in a given medium and is crucial in many scientific and engineering applications. The units for c2 are usually meters per second (m/s) or feet per second (ft/s). It cannot be negative as it represents a speed. However, there are limitations to using the formula, such as assuming a perfect gas and constant mass flow rate and velocity, which may not provide accurate results in certain situations.

To find c2, we need to use the formula c2 = mf * v^2. In this case, we have the values for both mf (20) and v (200v), so we can plug them into the formula.

c2 = 20 * (200v)^2

Next, we need to simplify the equation by squaring 200v.

c2 = 20 * 40000v^2

Then, we can multiply 20 by 40000 to get the final value for c2.

c2 = 800000v^2

So, the value of c2 is 800000v^2. This is how you can find c2 using the given values for mf and v. It is important to note that the units for c2 will depend on the units used for mf and v.
 

1. How do I find c2 with mf and v?

To find c2 with mf and v, you can use the formula c2 = mf x v. This formula represents the product of the mass flow rate (mf) and the velocity (v).

2. What is the significance of finding c2?

Finding c2 is important because it represents the speed of sound in a given medium. It is a crucial parameter in many scientific and engineering applications, such as aerodynamics and fluid mechanics.

3. What are the units for c2?

The units for c2 are usually meters per second (m/s) or feet per second (ft/s), depending on the units used for mass flow rate and velocity.

4. Can c2 be negative?

No, c2 cannot be negative. It represents a speed, and speed is always a positive value.

5. Are there any limitations to using the formula c2 = mf x v?

Yes, there are some limitations to using this formula. It assumes that the medium is a perfect gas and that the mass flow rate and velocity are constant. It may not provide accurate results for non-ideal gases or when there are variations in the flow rate and velocity.
