considering previous observation, suppose that a communication system is required to transmit 48 simultaneous conversations from site l1 to site l2 using "packets" of voice information. packets of information correspond to 10-ms segments of speech. (what should be the transmission speed of the packets in your system? )

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?
