18. If a vessel containing liquid moves downward with a constant acceleration equal to'g' then a) the pressure throughout the liquid mass is atmosphericb) there will be vacuum in the liquidc) the pressure in the liquid mass is greater than hydrostatic pressured) none of the aboveAns: a 19. When a liquid rotates at a constant angular velocity about a vertical axis as a rigidbody, the pressure intensity varies 20. An open cubical tank of 2 m side is filled with water. If the tank is rotated with anacceleration such that half of the water spills out, then the acceleration is equal to 21. A right circular cylinder open at the top is filled with liquid and rotated about itsvertical axis at such a speed that half the liquid spills out, then the pressure intensity atthe center of bottom is 22. The horizontal component of force on a curved surface is equal to the a) product of pressure intensity at its centroid and areab) force on a vertical projection of the curved surfacec) weight of liquid vertically above the curved surfaced) force on the horizontal projection of the curved surfaceAns: b 23. A closed tank containing water is moving in a horizontal direction along a straight line at a constant speed. The tank also contains a steel ball and a bubble of air. If the tank is decelerated horizontally, then i) the ball will move to the front ii) the bubble will move to the front Switchgear Protections Multiple Choice Questions a...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
