## How do you calculate CP from CV?

The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three translational degrees of freedom.

**Why is CP greater than CV for a gas?**

The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because when heat is added at constant pressure, the substance expands and work.

### What is difference between mass flow and volumetric flow?

Mass flow measures the number of molecules in a flowing gas. Volumetric flow measures the space that those molecules occupy. Because gases are compressible, volumetric flow rates can change substantially when pressure or temperature changes. Volumetric flow rate can also be called actual flow rate.

**How do you calculate process flow time?**

4. Flow-Time AnalysisCount the number of units produced over an extended period of time.R = number of units produced / duration of time period .Count the number of units of inventory at random points during the time period. Compute the average inventory (I).Compute flow time T =I/R.

#### What is throughput formula?

The throughput efficiency formula can be calculated more than one way, but the general formula is I = R * T. In other words, Inventory = Rate multiplied by Time, where “rate” is the throughput. But if you solve for R, you would get R = I / T, or Rate = Inventory divided by Time.

**How do you calculate capacity?**

The Easy Way: Total Production Quantity During a Time Period One of the easiest ways to measure capacity is to simply use the total production quantity for a given time period. For example, if your plant can produce an average of 20,000 gizmos per week, then your total capacity is 20,000 gizmos per week.
