# How to calculate the pressure of a tap?

### How to calculate the pressure of a tap?

HOW? ‘OR’ WHAT PROCEED: Once the junction between the faucet and the pressure gauge is tight and not leaking, attach the pressure gauge pressure water on the faucet using fittings and Teflon. Open the water fully. The pressure water is between 40 psi and 100 psi (1 psi= bars) or between 2.75 Bar and 6.89 Bar.

### What is the speed of a flexible pipe?

This flexible pipe, which connects a hydraulic pump to a distributor, must circulate 30 l/min under a pressure of 25 bars. The fluid velocity is 1 m/s. The chemical resistance and fluid temperature chart appears in the manufacturer’s catalog.

### How to know the pressure of a flexible pipe?

Always rely on the manufacturer to know the working pressures, temperatures and bend radii of flexible hoses. Flexible hoses, while fulfilling their role as fluid conductors, can also serve to absorb pressure changes since they inflate slightly.

### How to calculate the expansion force of a pipe?

1) Expansion forces: They are not absorbed by the compensator. The longitudinal stresses on the piping can reach considerable values ​​as we have already indicated in § 2.2.2. Reminder: P = = Newton

### How to choose a flexible pipe?

Remember that when selecting a flexible hose, the mechanic must consider the following four factors: – Resistance to pressure. – The inside diameter perpendicular to the velocity of the liquid. – Compatibility with the hydraulic fluid and surrounding products.
