[amp_mcq option1=”the length of pipe” option2=”the viscosity of fluid” option3=”the bulk modulus for the fluid” option4=”the original head” correct=”option3″]<\/p>\n
The correct answer is C. The bulk modulus for the fluid.<\/p>\n
The speed of a pressure wave through a pipe is given by the following equation:<\/p>\n
$$v = \\sqrt{\\frac{K}{\\rho}}$$<\/p>\n
where $K$ is the bulk modulus of the fluid and $\\rho$ is the density of the fluid. The bulk modulus is a measure of how difficult it is to compress a fluid, and the density is a measure of how much mass is contained in a given volume of fluid.<\/p>\n
The length of the pipe and the viscosity of the fluid do not affect the speed of a pressure wave. The original head is the pressure at the beginning of the pipe, and it also does not affect the speed of a pressure wave.<\/p>\n
The bulk modulus is the only factor that affects the speed of a pressure wave. This is because the speed of a pressure wave is determined by how quickly the fluid can be compressed. The higher the bulk modulus, the more difficult it is to compress the fluid, and the faster the pressure wave will travel.<\/p>\n","protected":false},"excerpt":{"rendered":"
