A 1:50 model of a spillway is to be tested in the laboratory. The discharge in the prototype spillway is 1000 m^{3}/s. The corresponding discharge (in m^{3}/s, up to two decimal places) to be maintained in the model, neglecting variation in acceleration due to gravity, is ______

A concrete gravity dam section is shown in the figure. Assuming unit weight of water as 10 kN/m^{3} and unit weight of concrete as 24 kN/m^{3}, the uplift force per unit length of the dam (expressed in kN/m) at PQ is _________

The base width of an elementary profile of gravity dam of height H is b. The specific gravity of the material of the dam is G and uplift pressure coefficient is K. the correct relationship for no tension at the heel is given by
