Compute the total consumptive use for a drainage basin by Penman’s formula. The slope of saturation vapour pressure V/s chart at 40°C is 2.95 mm of Hg/°C and the net incoming solar radiation is 5.705 mm of evaporative water/day. Assume, Ea = 18.07 mm/day and Psychrometric constant = 0.49 mm of Hg/°C.
