Pipeline A has oil of relative density 0.85 and pressure gauge reading at B is 330 kPa

A manometer, shown below, connects a pipeline (location A) to a pressure gauge (location B). Calculate the pressure in pipeline A. Neglect the weight of the air in your calculations. As part of your answer, you must clearly identify where Pascal's Law applies. Click on the information hotspots (i) on the image to obtain details of the density of the fluid in pipeline A and the pressure gauge reading at location B
