. 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.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
