[amp_mcq option1=”linearly with radial distance” option2=”as the square of the radial distance” option3=”inversely as the square of the radial distance” option4=”inversely as the radial distance” correct=”option3″]<\/p>\n
The correct answer is: C. inversely as the square of the radial distance.<\/p>\n
The pressure intensity at a point in a rotating fluid is given by the following equation:<\/p>\n
$$P = P_0 + \\rho \\omega^2 r^2$$<\/p>\n
where $P_0$ is the pressure at the center of the fluid, $\\rho$ is the density of the fluid, $\\omega$ is the angular velocity of the fluid, and $r$ is the radial distance from the center of the fluid.<\/p>\n
As you can see from the equation, the pressure intensity increases with the square of the radial distance. This is because the centrifugal force acting on a particle in a rotating fluid increases with the square of the radial distance. The centrifugal force pushes the particle away from the center of the fluid, which increases the pressure at that point.<\/p>\n
The other options are incorrect because they do not take into account the centrifugal force. Option A states that the pressure intensity varies linearly with radial distance. This is not correct because the pressure intensity increases more rapidly with radial distance than linearly. Option B states that the pressure intensity varies as the square of the radial distance. This is correct, but it is not the only factor that affects the pressure intensity. Option D states that the pressure intensity varies inversely as the radial distance. This is not correct because the pressure intensity increases with radial distance.<\/p>\n","protected":false},"excerpt":{"rendered":"
