Web18 okt. 2024 · As there is no drop-in elevation (no basement or lower level within the building), there will not be an increase in pressure due to elevation drop. This example will focus on the low pressure of 60 psi and will use this value to determine the allowable friction loss. A meter loss of 10 psi is assumed.
