An U-tube manometer shows a height difference of z1 between the two columns for a known gauge pressure P1 (both z1 and P1 in appropriate units). If the height difference between the two columns is 2z1, then the corresponding gauge pressure will be:
- A. P1/2
- B. 2P1
- C. P1
- D. 4P1
Answer: B. 2P1
