The volume of water remain in the tank after 30 seconds is 78.75 liters.
The given parameters;
- initial volume of water in Tank B, V₀ = 80 liters
- rate at which water is being drained, R = 2.5 liters per minute.
- time of water drain, t = 30 seconds
The amount of water drained after 30 seconds is calculated as follows;
[tex]V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters[/tex]
The volume of water remain in the tank after 30 seconds is calculated as follows;
V₂ = V₀ - V₁
V₂ = 80 liters - 1.25 liters
V₂ = 78.75 liters
Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.
