A storm sewer is mixed into a small stream. The stream before the mixing point has a NaCi concentration of 25 mg/L. If the storm sewer has a Nacl concentration of 1.8 g/L and the storm sewer flowrate is 2.5 L/min, calculate for the concentration of the salt in the stream after the discharge point (mixing point). The stream has a flowrate of 2.6 cu.m/s. Assume a complete mixing of the storm sewer flow and the stream flow. Assume also that the salt is nonreactive and that the system is at steady state.

What do you understand by the term evaporation? If you’re a civil engineering technologist where do you apply this evaporation in your civil engineering related projects explain it? A class-A pan was setup adjacent to a lake. The depth of water in the pan at beginning was 77cm. in that week, a rainfall of 37mm came and 15 mm of water was removed from pan to keep the water level in the specified depth. If the depth of water at end of the week was 186.89 mm, calculate pan evaporation. Using suitable pan coefficient, estimate lake evaporation in that week.
A one cell rapid sand filter tank has a loading rate 9.0 m/h, surface dimensions of 15*6 m. The sand and gravel depths are 70 cm and 60 cm respectively. The height of wash trough is 50 cm and the height of water above surface of sand is 2.0 m. Note that Shape factor of sand is 0.80 and stratified bed porosity is 0.50. a) What flow rate (m³/sec) does the filter handle during production? b) What is the total height of filter basin (m)? c) Calculate the head loss if the value of this term [2 (Co fid)] equal to 105700. d) In your opinion this filter tank specified the Saudi specifications?
