                Because in formula velocity is sound velocity and sound velocity is equal to root bulk modulus upon density so density upon root density is equal to root density.

                Given answer is current. Because in hammer blow conditions pressure is equal to square root of (density * velocity square * bulk modulus).

                For water hammer case pressure equal V root density/root (1/k+D/tE) so pressure is directly proportional to root density.

                For rigid pipe rise in pressure due to sudden closer of valve is,
P= density x velocity x √(bulk modulus/density).
                P= density x velocity x √(bulk modulus/density).

                Pressure= density x velocity x celerity.
c= √k/density.
Solve for the values we get option C is correct.
                c= √k/density.

                That depends on pipe is rigid or elastic for rigid:- option A is correct.
Elastic:- option C is correct.
                Elastic:- option C is correct.

                C= √k/density.
Pressure directly proportional to. Density *C.
So, the answer is √density.

                The Formula is √bulk modulus/density.
That's why the answer is D.

                The answer is d.
Because, C = square root (bulk modulus/density).
                Because, C = square root (bulk modulus/density).

                How this possible? Pressure = (density * length * velocity)/time.
