What is the relationship between shower head flow rate and pressure, and how does it impact the overall performance of a shower system?

The relationship between shower head flow rate and pressure is that as flow rate increases, pressure typically decreases. This can impact the overall performance of a shower system by affecting the strength and consistency of the water stream. Higher flow rates may result in a weaker water pressure, while lower flow rates can lead to a stronger pressure but potentially less water volume. Balancing flow rate and pressure is important for achieving an optimal shower experience.
