1.In a given month, a watershed with an area of 1500 m^2 received 100 cm of precipitation. During the same month, the loss due to evaporation was 15cm. Ignore losses due to transpiration and infiltration due to ground water. What would be the average rate of flow measured in a gage at the outlet of the watershed in m^3/day?
2.the player kicks a football with an initial speed of 90 ft/s. determine the time the ball was in the air and the angle of the kick. the distance is 126ft
3.The frame shown consists of four wooden members, ABC, DEF, BE, and CF. Knowing that each member has a 2 3 4-in. rectangular cross section and that each pin has a 12 -in. diameter, determine the maximum value of the average normal stress (a) in member BE, (b) in member CF.
It the mean annual runoff of a drainage basin of 10000 km^2 is 140 m^3/s, and the average annual precipitation is 105 cm, estimate the ET losses for the area in 1 year. What are your assumptions? How reliable do you think this estimate is?
