Information about A closed tank containing water to a depth of 1.5 m falls vertically with an acceleration of 2 m/s2. The Civil Engineering (CE) exam syllabus. The Question and answers have been prepared Can you explain this answer? for Civil Engineering (CE) 2023 is part of Civil Engineering (CE) preparation. What is the pressure at the bottom of the tank?a)12.5 kN/m2b)13.3 kN/m2c)11.7 kN/m2d)10.5 kN/m2Correct answer is option 'C'. Therefore, the pressure at the bottom of the tank is 17.7 kN/m2.Ī closed tank containing water to a depth of 1.5 m falls vertically with an acceleration of 2 m/s2. To convert the pressure from N/m2 to kN/m2, we divide by 1000:
Now, we can substitute the values into the formula: In this case, the net acceleration is 9.8 m/s2 + 2 m/s2 = 11.8 m/s2. The net acceleration is the sum of the acceleration due to gravity and the acceleration of the tank. Given that the tank falls vertically with an acceleration of 2 m/s2 and the depth of the water is 1.5 m, we need to consider the net acceleration acting on the water. The acceleration due to gravity, g, is 9.8 m/s2. In this case, the fluid is water and its density is approximately 1000 kg/m3. Where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid column. We can determine the pressure at the bottom of the tank using the formula: Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it. To find the pressure at the bottom of the tank, we can use the concept of hydrostatic pressure.
