Prime number indicator: in this activity, you will design a circuit that indicates whether a number between 0 through 15 is a prime number or not. a prime number is defined as a number that can be divided only by itself and 1. by definition, the numbers 0 and 1 are not prime. the circuit must have four binary inputs a, b, c, d, and one output, g. the output signal g is true (g = 1) if the input represents a prime number and is false (g = 0) otherwise.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Journeyman training is usually related (clo2) a)-to specific tasks b)-to cost analysis of maintenance task c)-to control process to ensure quality d)-to installation of machinery

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
