One method of ensuring reliability in data transmission systems is to transmit a parity bit along with every nibble, byte, or word of binary data transmitted. The parity bit confirms whether an even or odd number of 1s were transmitted in the data. In even-parity systems, the parity bit is set to 1 when the number of 1s in the transmitted data is odd. Odd-parity systems set the parity bit to 1 when the number of 1s in the transmitted data is even. Assume that a parity bit is transmitted for every nibble of data. Design a logic circuit that checks the nibble of data and transmits the proper parity bit for both even- and odd-parity systems.
A gas mixture at 675.0°C and 113 kPa absolute enters a heat exchanger at a rate of 69.0 m3/hr. The gas leaves the heat exchanger at 245.0°C. The change in enthalpy of the gas during the cooling process is -6.80 kJ/mol.
