1. The problem statement, all variables and given/known data The following question is from ExamKrackers Physics [an MCAT prep book]. An ideal fluid with specific gravity of 1.0 is passed through a pipe. Along the length of the pipe shown above are attached 3 vertical pipes which are sealed off as shown above. If now a different ideal fluid with a specific gravity of 2.0 is passed through the pipe at the same volume flow rate the pressure at any point in the pipe would: a. decrease by a factor of 2 b. remain the same c. increase by a factor of 2 d. more information is required 2. Relevant equations K = P + pgy + 1/2*pv^2 3. The attempt at a solution Based on bernoulli's equation above if you increase rho, pressure would have to decrease since the terms of bernoulli's equation sum to a constant. The answer given by Examkracers is that [c] the pressure increases by a factor of 2. I can't seem to see why this would be true. Any help would be greatly appreciated.
