The inclined manometer shown below is used to measure the pressure difference in a pipeline carrying oil (sg = 0.91). the manometer tube is inclined at an angle of 30° to the horizontal, and the pressure taps on the pipe are 5 in. apart. the manometer fluid is mercury (sg of 13.6). (a) derive a formula for h, in terms of l and θ. (b) if the manometer reading (l) is 3 in. what is the pressure drop in the pipe in pa, and in psi?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
