. 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.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
