meters of water @ 4°C to megapascals conversion

How to convert meters of water @ 4°c to megapascals?

Meters of water @ 4°C (also known as meters of water column or mwc) is a unit of pressure derived from the height of a water column. To convert meters of water column to megapascals (MPa), you need to understand the relationship between these two pressure units.

1 meter of water column (mH2O) @ 4°C is approximately equal to 9.80665 kilopascals (kPa).

To convert from meters of water to megapascals:

$1 \text{ meter of water} = 9.80665 \, \text{kPa} = 0.00980665 \, \text{MPa}$

Conversion Steps:

1. Convert the pressure in meters of water to kilopascals using the specific gravity at 4°C.
2. Convert kilopascals to megapascals.

Example Conversion:

$1 \, \text{mH2O} = 9.80665 \, \text{kPa} = 0.00980665 \, \text{MPa}$

Real-World Examples:

10 meters of water @ 4°C:

$10 \, \text{mH2O} = 10 \times 9.80665 \, \text{kPa} = 98.0665 \, \text{kPa} = 0.0980665 \, \text{MPa}$

50 meters of water @ 4°C:

$50 \, \text{mH2O} = 50 \times 9.80665 \, \text{kPa} = 490.3325 \, \text{kPa} = 0.4903325 \, \text{MPa}$

100 meters of water @ 4°C:

$100 \, \text{mH2O} = 100 \times 9.80665 \, \text{kPa} = 980.665 \, \text{kPa} = 0.980665 \, \text{MPa}$

Practical Applications:

• Water Towers: Water pressure in high-rise buildings or water towers. For instance, a water tower that creates a pressure of 30 meters of water column would exert: $30 \, \text{mH2O} = 30 \times 9.80665 \, \text{kPa} = 294.1995 \, \text{kPa} = 0.2941995 \, \text{MPa}$

• Engineering and Hydraulics: Pipe systems, pump specifications, and hydraulic systems often use this measure to denote the pressure head in the system. The design might include converting meters of water column to MPa for safety and efficiency.

By understanding how to convert meters of water to megapascals, engineers can ensure that the systems they design can safely and efficiently handle the pressures involved.
