Microprocessor: Assume, a switch is connected to bit 0 (LSB) of the input port (address $9000). If that bit is one (1), the switch is ON. A light bulb is connected to bit 7 (MSB) of out port (address $8000). A one (1) makes the bulb ON. If the switch is ON, we are going to make the bulb ON otherwise keep it OFF. Write an input/output program to control the light bulb.

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
