P2 Air P1 Water h1 Mercury h2 What is the pressure difference, P1 - P2, in kPa? Discussion: How much larger would the manometer have to be to measure using a less environmentally hazardous material such as an oil with a specific gravity of 0.83? Discuss the practical consequences. (pmercury 13,560 kg/m8; pwater=998 kg/m3; Pair=1.2 kg/m3) Ancuor
