Design a 2-bit carry ripple adder assuming you only have half adder circuits and OR gates to work with. Draw up a schematic for your design using half adder building blocks and OR gates. Be sure the clearly label all inputs and outputs of your blocks.\

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
