Derive the single-stage delay of the ring oscillator from the time period of socillation that you see in experiment 2. if the delay of one inverter is 10ns, what will be the frequency of the signal generated from a 21 stage ring oscillator?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
