The volumetric flow through a pipe is determined as V=vA where V = volumetric flow, in cu ft/sec v = mean fluid velocity, ft/sec A = cross-sectional flow area, sq ft Create an Excel worksheet that can be used to answer the following questions: (a) What will be the volumetric flow through the pipe if the mean fluid velocity is 10 ft/sec and the pipe has an outer diameter of 4.94 inches and a thickness of 0.25 inch?

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Answershe should not have multiplied the sulfur atoms by the subscript 4

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
