Problem
1. A manometer shows a pressure difference of 1 m of liquid mercury. Find ?P in kPa.
2. 8 Blue manometer fluid of density 925 kg/m3 shows a column height difference of 3-cm vacuum with one end attached to a pipe and the other open to P0 = 101 kPa. What is the absolute pressure in the pipe?
3. What pressure difference does a 10-m column of atmospheric air show?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
