Given the pipe diameter and pressure difference, how can the gas flow rate or velocity in a pipe be calculated?

Given the pressure difference of the air in the pipeline and its diameter, how can the flow velocity of the gas within the pipeline be calculated? For example, in a DN25 pipeline with an inlet pressure of 0.5 MPa and an outlet pressure at atmospheric level, how can the flow velocity and volume flow rate be determined?
The Huawei App Market has a software called Pipe Pump Comprehensive Calculation, which can determine the flow velocity and flow rate in pipes with fixed pressure and length
Generally, the flow velocity of compressed air is 15 meters per second; the flow rate through a dn25 pipe is roughly 2 cubic meters per hour. This depends mainly on the gas production capacity of the compressor or the total amount of steam generated. How much flow can such a thick tube handle?
The pipe length needs to be known; the flow rate can be determined using an iterative method
Isn’t there an equation that can be used to calculate it directly?
Based on the length of the pipe, calculate the pressure drop per unit length; if it is relatively short, then the flow rate is essentially close to the critical flow velocity. The flow rate can be determined from the exit flow velocity
