Calculate the usage volume and duration of compressed gas flow based on cylinder and usage pressures, and gas flow rate.

Compressed Gas Flow Duration

Purpose

This calculator function helps you determine the duration for which a compressed gas in a cylinder will last based on the flow rate at which the gas is being used.

Use Cases

You can use this function to calculate how long a specific amount of compressed gas will last based on the flow rate at which it is being used.

How to Use

1. Enter the required values in the input fields below.
2. Click on the "Calculate" button to see the results.

Input Values

1. Cylinder Size: The size of the gas cylinder. Default unit is liter.
2. Cylinder Pressure: The pressure of the gas in the cylinder. Default unit is MegaPascal.
3. Usage Pressure: The pressure at which the gas is being used. Default unit is MegaPascal.
4. Gas Flow Rate: The rate at which the gas is being used. Default unit is milliliter per minute.

Output Values

1. Usage Volume: The volume of gas that will be used. Unit of measurement will be the same as the Cylinder Size.
2. Usage Duration: The duration for which the gas will last. Unit of measurement is hours.

Any other Instruction

• Make sure to enter the values in the correct units as mentioned in the input field labels.
• Double-check the input values before clicking on the "Calculate" button.

Calculation Steps

1. Calculate the usage volume based on the cylinder size, cylinder pressure, and usage pressure.
2. Determine the usage duration by dividing the usage volume by the gas flow rate.

Technical Parameters

• cylinder_size, cylinder_pressure, usage_pressure, gas_flow_rate

Return Values

• Usage Volume, Usage Duration

Example Expressions

You can use the following expressions to directly evaluate in a non-interactive manner using eval(): 1. gas_flow('47.0 l', '20.0 MPa', '0.45 MPa', '600 mlpm') 2. gas_flow('30.0 l', '15.0 MPa', '0.30 MPa', '400 mlpm')
