A 2 m wide rectangular channel is carrying a discharge of 30 m3/s at a bed slope of 1 in 300. Assuming the energy correction factor as 1.1 and acceleration due to gravity as 10 m/s2, the critical depth of flow (in meters) is __________ (rounded off to 2 decimal places).
The number of degrees of freedom for a natural open channel flow with a mobile bed is
A 30 cm diameter well fully penetrates an unconfined aquifer of saturated thickness 20 m with hydraulic conductivity of 10 m/day. Under the steady pumping rate for a long time, the drawdowns in two observation wells located at 10 m and 100 m from the pumping well are 5 m and 1 m, respectively. The corresponding pumping rate (in m³/day) from the well is _____________ (rounded off to 2 decimal places).
The dimension of dynamic viscosity is :
