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.
