× 10^-6 m^2/s. The depth of the tank is 4 meters. Calculate the surface area of the settling tank.
To calculate the surface area of the settling tank, we can use the formula:
Surface Area = Surface Overflow Rate / (Kinematic Viscosity × Depth)
Plugging in the given values:
Surface Area = 20000 litre/m^2 per day / (1.01 × 10^-6 m^2/s × 4 m)
First, we need to convert the surface overflow rate from liters to cubic meters:
Surface Overflow Rate = 20000 litre/m^2 per day × (1 m^3 / 1000 litre) × (1 day / 24 hours)
Surface Area = (20000 / 1000) m^3/m^2 per hour × (1 hour / 3600 seconds) / (1.01 × 10^-6 m^2/s × 4 m)
Simplifying:
Surface Area = 0.00556 m^3/m^2 per second / (1.01 × 10^-6 m^2/s × 4 m)
Surface Area = 0.00556 m^3/m^2 per second / (4.04 × 10^-6 m^3/s)
Surface Area = 1371.28 m^2
Therefore, the surface area of the settling tank is approximately 1371.28 square meters.
To calculate the surface area of the settling tank, we can use the formula:
Surface Area = Surface Overflow Rate / (Kinematic Viscosity × Depth)
Plugging in the given values:
Surface Area = 20000 litre/m^2 per day / (1.01 × 10^-6 m^2/s × 4 m)
First, we need to convert the surface overflow rate from liters to cubic meters:
Surface Overflow Rate = 20000 litre/m^2 per day × (1 m^3 / 1000 litre) × (1 day / 24 hours)
Surface Area = (20000 / 1000) m^3/m^2 per hour × (1 hour / 3600 seconds) / (1.01 × 10^-6 m^2/s × 4 m)
Simplifying:
Surface Area = 0.00556 m^3/m^2 per second / (1.01 × 10^-6 m^2/s × 4 m)
Surface Area = 0.00556 m^3/m^2 per second / (4.04 × 10^-6 m^3/s)
Surface Area = 1371.28 m^2
Therefore, the surface area of the settling tank is approximately 1371.28 square meters.
