Direction of Rotation. Iif the calculated result is negative, the driver and follower will rotate in opposite directions; otherwise, a non-negative answer means tha both will rotate in the same direction. Figures 19 - 22 are used to obtain the speed ratios when there are two driving members rotating at different speeds. These are Compound Drive ...

Using round function to calculate a ratio is also a useful method. This is especially useful when you want to calculate ratio with decimals for accurate comparison. Here we have values in which higher value is not divisible with the smaller value. So, in this situation instead of using them as they are you can divide them and show the final ratio with decimals. Just insert the below formula ...

Key Points To Keep In Mind: T he ISTD must be of known pur ity (by certifi ed method), have a similar respon se as the sample and not interfere with the analysis.; The calculated amount of your unknown samples is directly related to the amount of the ISTD used. The results are calculated based on the ratio of the responses for both peaks (i.e. std and unknown).

Calculating the Ratio. The air to fuel ratio is the property of fuel and chemical composition of the fuel that defines the value for this ratio. Most of the fuels we use in internal combustion engines are hydrocarbons, and their burning will obviously result in the release of hydrogen and carbon as residuals, along with heat and pressure. Below is an example of the oxidation reaction of ...
