PROBLEM 12 A canal and a river run parallel, an average of 350 fee apart. The elevation of water in the canal is El. 124 and in the river El. 1180. A stratum of sand intersects both the river and the Canal below their water levels. The sand is 12 feet thick and is sandwiched between Strata of impervious clau. Compute the see page loss.. From the canal in cubic feet per second per mile it the Sand's permeability is 0.083 cm per sec. PROBLEM 13 Given a block of soil 12cm long and 6 sq.cm. in Cross-section. The water level at one end of the block is 20 cm above a fixed plane and at the other end is 3cm above the same plane. The flow rate is 2 cm in 1.5 minutes. Compute the soil permeability in feet per minute. Problem 14 Determine the pressure, elevation and total head at the entrance end, exit end and point of the sample. T- Case I CASE I Case II
