Title: Calculation of Pressure Difference using Double-fluid Manometer

Introduction:
A double-fluid manometer is a device that measures the pressure difference between two points in a fluid system. It consists of a U-shaped tube filled with two different fluids of known specific gravities. The pressure difference is determined by measuring the difference in height of the two fluids in the tube.

Given Data:
Fluid heights: h1 = 150mm, h2 = 50mm
Specific gravities: oil = 0.8, water = 1.0

Calculation:
1. Determine the pressure difference between the two fluids using the formula:
Pressure difference = (specific gravity of fluid 2 - specific gravity of fluid 1) x height difference
2. Substitute the given values into the formula:
Pressure difference = (1.0 - 0.8) x (150 - 50) mm
3. Solve for the pressure difference:
Pressure difference = 20 x 100 mm
Pressure difference = 2000 Pa or 2 kPa

Conclusion:
The pressure difference between the oil pipe and water pipe is 2 kPa. This can be determined using a double-fluid manometer by measuring the difference in height of two fluids of different specific gravities.
