PROBLEM I - The pressure difference between an oil pipe and water pipe is measured by a double-fluid manometer, as shown in the figure 1. The specific gravities are 13.5 for mercury, 1.26 for glycerin, and 0.88 for oil. Take the standard density of water to be pw =1000 kg/m³. The gauge pressure at B is 10kPa. Water SG=1.0 a) h = y *p*P b) h= y*g*P c) h = P/ d) h= y*P/g e) None of the above Mercury SG-13.5 55 cm 28cm Glycerin SG-1.26 10 cm 12 cm Figure 1 Oil SG=0.88 Question 1: Which equation relates the gauge pressure P to the depth h in a fluid with density p, and specific weight, y?
