Water at 25 deg C (998 kg/m 3 ) flows at 10 m 3 /s through a straight pipe of an ID of 1.38 m to 2 m-ID. Consider the level of the entrance and terminal bottom walls of the pipe equal, neglecting the effects of potential energy. In addition, the shaft work is zero. Calculate the pressure drop assuming the pipe is a commercial steel pipe. Suppose there are no friction losses, what is the theoretical pressure drop?

Hi, I think you forgot to divide the answer by 2 as indicated in your initial formula. Moreover, I tried solving the problem using the formula I attached as image here and I got a positive value of the answer you came up with. What answer would be the right one? Also, please explain the cause and effects of having that certain value of theoretical pressure drop in the problem. Thank you so much!
