Speed of sound in fresh water at 20 degrees Celsius

The speed of sound in fresh water is $1\ 481\ \text{m/s}$ at 20 degrees Celsius which is sligltly more than $4.3$ times the speed of sound in air at 20 degrees Celsius.

Speed of sound at 25 degrees Celsius

The speed of sound in air is $346.13\ \text{m/s}$ at 25 degrees Celsius.

How to convert Speed of sound in fresh water at 20 degrees Celsius to Speed of sound at 25 degrees Celsius

$$\text{Speed}_{\text{Speed of sound₂₅}} = \text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} \cdot 4.278739202033917892121457255944298$$

Examples

Example 1

Convert $30.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{Speed of sound₂₅}$.

$$\text{Speed}_{\text{Speed of sound₂₅}} = 30.0 \cdot 4.278739202033917892121457255944298$$

$$\text{Speed}_{\text{Speed of sound₂₅}} = 128.362176$$

$$\therefore \ 30.0\ \text{Speed of sound₂₀ (fresh water)} = 128.362176 \ \text{Speed of sound₂₅}$$

Example 2

Convert $65.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{Speed of sound₂₅}$.

$$\text{Speed}_{\text{Speed of sound₂₅}} = 65.0 \cdot 4.278739202033917892121457255944298$$

$$\text{Speed}_{\text{Speed of sound₂₅}} = 278.118048$$

$$\therefore \ 65.0\ \text{Speed of sound₂₀ (fresh water)} = 278.118048 \ \text{Speed of sound₂₅}$$

Example 3

Convert $110.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{Speed of sound₂₅}$.

$$\text{Speed}_{\text{Speed of sound₂₅}} = 110.0 \cdot 4.278739202033917892121457255944298$$

$$\text{Speed}_{\text{Speed of sound₂₅}} = 470.661312$$

$$\therefore \ 110.0\ \text{Speed of sound₂₀ (fresh water)} = 470.661312 \ \text{Speed of sound₂₅}$$

Example 4

Convert $130.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{Speed of sound₂₅}$.

$$\text{Speed}_{\text{Speed of sound₂₅}} = 130.0 \cdot 4.278739202033917892121457255944298$$

$$\text{Speed}_{\text{Speed of sound₂₅}} = 556.236096$$

$$\therefore \ 130.0\ \text{Speed of sound₂₀ (fresh water)} = 556.236096 \ \text{Speed of sound₂₅}$$

Example 5

Convert $195.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{Speed of sound₂₅}$.

$$\text{Speed}_{\text{Speed of sound₂₅}} = 195.0 \cdot 4.278739202033917892121457255944298$$

$$\text{Speed}_{\text{Speed of sound₂₅}} = 834.354144$$

$$\therefore \ 195.0\ \text{Speed of sound₂₀ (fresh water)} = 834.354144 \ \text{Speed of sound₂₅}$$
