#### Query :

Calculate the differential strain sensed by the extent transmitter at three totally different water ranges on this boiler steam-drum stage measurement system: The measurable factors are zero%, 50%, and 100% of transmitter vary.

Assume a density for (sizzling) boiler drum water of 36 lb/ftthree , a density for steam within the drum of seven lb/ftthree , and a density for (heat) water within the “moist leg” of 61.eight lb/ft3 . If the stress on the “low” (L) facet of the transmitter is larger than the stress on the “excessive” (H) aspect, make sure you categorical the differential strain amount as a adverse quantity.

Credit score shall be given for accurately calculating every of the differential pressures:

• (6 factors) Transmitter ∆P at zero% water stage     = _______”W.C.
• (6 factors) Transmitter ∆P at 50% water degree   = _______”W.C.
• (6 factors) Transmitter ∆P at 100% water degree = _______”W.C.
