The two pipes (A and B) contain the same liquid with a density of 923 kg/m3. The differential pressure reading in the manometer is found to be h = 0.3m of mercury (density = 13550 kg/m3). Due to changes in pumping, pressure in pipe A increases by 10kPa. What should be the value of hin the manometer at that time?

Liquid benzene and liquid n-hexane are blended to form a stream flowing at a rate of 1700 lbm/h. An on-line densitometer (an instrument used to determine density) indicates that the stream has a density of 0.810 g/mL. Using specific tractors from Table B. 1, estimate the mass and volumetric feed rates of the two hydrocarbons to the mixing vessel (in U. S. customary units). State at least two assumptions required to obtain the estimate from the recommended date.
