The storage (S, m³) and outflow rate (O, m³/s) of an outflow structure of a reservoir can be described by the relationship S/10,000 = O. At time equal to zero, the inflow rate, the outflow rate, and the storage can be assumed to be zero, compute the outflow rate from the storage at the end of the two hours when the inflow rate was 500 m³/s.

HYDRAULICS Convert all units in SI. Round off to 2 significant figures. Compute the discharge of water over a cipolletti weir 5.0 ft long under a head of 0.85 ft. Compare with the discharge over a standard rectangular weir with the same length and head.
The water balance is defined by the general hydrologic equation, which is basically a statement of the law of conservation of mass applied to the hydrologic cycle. In its simplest form, this equation reads I= O + AS. where l is total inflow. O is total outfiow and AS is change in storage. In a month of 30 days, a lake received an average inflow of 6 m^3/s from surface runoff. In that same period, outfilow from the lake had an average value of 6.5 m^3/s. Further, the lake received a rainfall of 145 mm. evaporation of 6.10 cm and seepage loss was 2.5 cm in that month. The average lake surface is 5000 ha. Compute for the change in water elevation in the lake at the end of that month in centimeters. If it is a LOSS, indicate this by preceding your answer with a negative sign. "
