. Design a buffer to rapidly drive a capacitive load of 1000 fF. Assume that the signal source is a unit inverter with Cin of 0.666fF. Determine the number of inverters in the buffer, and how many times bigger than a unit inverter each inverter is. It does not matter whether the buffer is inverting or non-inverting.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
