What is the average 2-year 3-h rainfall on an area of 508km² if the point value is 50mm

A lake of surface area 500 Acres received a daily average rainfall equals to Your Roll No (R) mm for a whole month. Direct inflows to this lake during this month were; R, 2R, 1.5R and 3R (in cusecs). Daily evaporation loss during this month was 1R cm/day. Later it was found that the rain gauge was inclined at an angle of 10 degree with the vertical. Direct outflow during this month was 0.25R cusecs/day. Assume the sides of the lake as vertical with initial water depth of 100ft at start of the month. Find the final storage of the lake at the end of the month. Also find the change in storage of the lake and rate of change of storage? Find Your answers in Acre-ft and Acre-ft/month, respectively NOTE: Here R=20

Use 4 decimal places whenever rounding off. Using Isohyetal Method, calculate the average rainfall of the given section. A = 10 + (25 / 8) = 13.13 %3D B = 14 – (25 / 11) = 11.72 C = 20 – (25 / 10) = 17.5 Amm 23.5km2 Bmm 18.7km? 32.2km Cmm 29.5km 38km2) 23mm 17mm 11. 7km 14mm
