Thumbs up for telling me if I'm right or wrong

Consider an 71 m deep lake. The pressure difference between the top and bottom of the lake in kPa is... (Report your answer to 0 decimal places.) The atmospheric pressures at the top and the bottom of a mountain are read by a barometer to be 85 and 98.7 kPa. If the average density of air is 1.25 kg/m3, what is the height of the mountain in meters? Report your answer to 0 decimal places. The pressure drop in a duct is to be measured by a differential oil manometer. If the differential height between the two fluid columns is 4.4 cm and the density of oil is 860 kg/m3, what is the pressure drop in the duct in Pa? Report your answer to 0 decimal places.

Explanation / Answer

ccording to the chegg guidelines I am allowed to answer only 1 question at a time .

Question 5) Here we need to find the value of the pressure difference b/w the top and the bottom.

Pressure (Diff) = density * g * h = 1000 * 9.8 * 71 m = 695800 Pa or 695.800 Kpa ======ANSWER)
