A tank with two inflows is filled with water at varying speeds. If inflow velocities are 0.5 m/s and 0.8 m/s with diameters of 25 mm and 35 mm respectively, calculate the change in water height over a 5-minute interval if the tank area is 2 m².
💡 Hint: Use the inflow formula to find volumes, then convert to height over time.
You have a channel where the upstream velocity is 0.6 m/s and downstream is 0.4 m/s, with a channel width of 1.5 m. Determine the seepage rate given the channel's average depth is 0.2 m.
💡 Hint: Calculate flow before and after across given areas.
