Show formula of venture meter ?

The formula for calculating the venture meter is as follows:

Venture Meter = (Total Investment / Total Revenue) * 100

Where:
- Total Investment is the total amount of money invested in the venture
- Total Revenue is the total revenue generated by the venture

The venture meter is a metric used to measure the return on investment for a venture or business. It indicates how efficiently the venture is utilizing its resources to generate revenue. A higher venture meter value indicates a more successful venture, while a lower value indicates that the venture may not be generating enough revenue to justify the investment.

$$ Q = cA\sqrt{2gh(H-h)} $$

Where:
- Q is the flow rate in cubic meters per second
- c is the coefficient of discharge, which is a dimensionless constant that depends on the shape of the meter
- A is the area of the throat of the meter in square meters
- g is the acceleration due to gravity in meters per second squared
- h is the difference in height between the upstream and downstream water levels in meters
- H is the total height of the meter in meters
