Use Green-Ampt method to compute the intriltration rate and cumulative infiltration for a for a silty clay soil at 0.25-hr increments up to 4 hr from the beginning of infiltration. Assume: Initial effective saturation = 30% and continuous ponding.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
