The below figure shows a pipe with a circular cross section of diameter 5 cm on the left end and a square cross section with diagonal 5 cm on the right end. Water enters the left end with a velocity 20 m/s and leaves the right end with a velocity V2. Find V2 (neglect losses in the pipe).

• A. V2 cannot be found as the length of the pipe is not given
• B. V2 cannot be found as the intermediate cross sections are not given.
• C. 31.41 m/s
• D. 20 m/s
• E. .a) V2 cannot be found as the length of the pipe is not givenb) V2 cannot be found as the intermediate cross sections are not given.c) 31.41 m/sd) 20 m/s
