Influence from bends on a pressure-time measurement

Jørgen Ramdal; Pontus Jonsson; Torbjørn Nielsen

One of the criteria for using the pressure-time method is that there is a straight pipe between the measurement cross sections. If the physical influences from a bend were known the method could be ...
