1.A sample of coarse sand is tested in a constant head permeameter.The sample is 20 cm high and has a diameter of 8 cm. Water flows through the soil under a constant head of 1 m for 15 minutes. The mass of discharged water was found to be equal to 1.2 kg. Determine the hydraulic conductivity for this soil sample. What would be the value of D10 for this sand? Consider C = 1.2.

2.A horizontal channel 4 m wide carries a discharge of 16 m3/s. Determine whether a jump may occur at an initial depth of 0.5 m or not. If a hydraulic jump occurs, determine the sequent depth (conjugate depth) to this initial depth. Also determine the energy loss in the hydraulic jump.
