Question
  1. Calculate the absolute pressure in kPa at the water tank when a mercury manometer shows a differential height of 9768 mm (Figure 1). The atmospheric pressure is 1.1 kPa, the specific gravity of mercury is 13.6 and the density of water is 1000 kg/m3. 
  2. Pressure drop is measured when water flows downward in a pipe at 45°, as shown in Figure 2. The manometer uses a manometric fluid of density 9768 kg/m3.  What is the total pressure drop in terms of P1 - P2 in Pa?
