In a tank divided by a partition into two compartments, enters the water flow rate Q = 28 l/s (Fig. 12). The partition has an opening with a diameter d1 = 75 mm. From the second compartment the water flows into the atmosphere through the outer cylindrical nozzles of diameter d2 = 60 mm. To determine at what levels h1 and h2 will be water in the compartments when reaching the stationary regime. The density of water is 1000 kg/m3. Initial data for calculation are given in the table.
