Consider a rice field of 100 hectares located at latitude of 42°N. The growing season for the rice is from January to March. The consumptive use coefficient for the rice is The following table contains the climatic data from a nearby weather station.

Month	January	February	March
Mean temp. (°F)	54	60	75
Total rainfall (mm)	90	120	130

(a) Use the Blaney–Criddle method to estimate the total consumptive use of the rice crop in the field.

(b) Estimate the volume of irrigated water (in m3) needed for each of the months during the rice-growing season.
