The single plate efficiency, also known as the Moffrey plate efficiency, refers to the ratio of the composition change value of the gas or liquid phase before and after passing through an actual layer of tray to the composition change value before and after passing through a theoretical layer of tray.

Gas phase veneer efficiency according to the formula

Calculate

Where, E_MV Is the gas phase plate efficiency; y_n Is the gas phase composition rising from the n-th plate, mole fraction; y_n+1 Is the gas phase composition rising from the n+1 plate, mole fraction; y_n^* Is the liquid phase composition x under the n-th plate flow_n Gas phase composition of phase equilibrium, mole fraction

Please enter the function in the following table format. Functions or expressions can be nested in the function
For example: 3.14 * pow (5 * lg (4 * 8), 4+8 * sin (30))
The unit of trigonometric function is degree
