Question 26 (1 point) Listen In the multi-fluid manometer below, oil has specific gravity of 0.850 and mercury has specific gravity of 1.36. Select all the correct answers about the relations in pressure at different points Oil Air 1 Water 2 16 .3 9 Mercury OP, P8 Question 27 (1 point) isten Consider a submarine cruising 49 m below the free surface of seawater whose density is 1,023.2 kg/m . How much (in kPa) is the increase in the pressure exerted on the submarine when it dives to a depth of 109 m below the free surface? Please pay attention, the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s2 Your Answer: Question 28 (1 point) Listen The atmospheric pressures at the top and the bottom of a mountain are read by a barometer to be 91.8 kPa and 106,3 kPa. If the average density of air is 1.26 kg/m what is the height of the mountain (in m)? Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s? Your Answer: Answer Question 29 (1 point) Listen The pressure drop in a duct is to be measured by a differential oil manometer. If the differential height h between the two fluid columns is 3.1 cm and the density of oil is 865.1 kg/m what is the pressure drop in the duct (in Pa)? A section or flow device Fluid Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s Your
