===== Function Naming =====

Lib.Mervis.v1_0.VelocityToFlow_m3ph

===== Description =====

A function used to convert pipe flow velocity to volumetric flow rate.

==== Required Project References ====

  * Lib.Mervis

===== Usage in ST =====

<code>
program test
    var
        velocity : real;
        flow : real;
    end_var

    flow := lib.mervis.v1_0.VelocityToFlow_m3ph(Velocity_mps := velocity, diameter := 0.1);
end_program
</code>

===== Inputs =====

|Name         |Data Type|Retain|Mandatory Connection            |Meaning|
|Velocity_mps |real     |No    |Yes                             |Velocity in the pipe in meters per second|      |
|Diameter     |real     |No    |No                              |Pipe diameter in meters               |      |

===== Outputs =====

|Name  |Data Type                                               |Meaning|
|=>    |real                                                    |Calculated volumetric flow in cubic meters per hour|      |

===== Notes =====

To obtain the mass flow rate in kilograms per hour, the result of the function should be multiplied by the density of the substance in kilograms per cubic meter.
