A long iron rod initially at a temperature of 20°C has one end dipped in boiling water (100°C) at time, t = 0. The curved surface of the rod is insulated so that heat conduction is one dimensional i
If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical
Consider the following statements:For a master-slave J-K flip-flop, the toggle frequency is the maximum clock frequency at which the flip-flop will toggle reliably.the data input must precede the cloc
The towns A, B and C are on a straight line. Town C is between A and B. The distance from A to B is 100 km. How far is A from C I. The distance from A to B is 25% more than the distance from C to B
The pressure, temperature and velocity of air flowing in a pipe are 5 bar, 500 K and 50 m/s, respectively. The specific heats of air at constant pressure and at constant volume are 1.005 kJ/kgK and 0.
A and B are standing at a distance of 20 km from each other on a straight East-West road. A and B start walking simultaneously, eastwards and westwards respectively, and both cover a distance of 5 km.
A rocket motor has a chamber pressure of 100 bar and chamber temperature of 3000 K. The ambient pressure is 1 bar. Assume that the specific heat at constant pressure is 1 kJ/kg-K. Also assume that the
One calorie is defined as the heat required to raise the temperature of 1 gm of water by 10C in a certain interval of temperature and at certain pressure. The temperature interval and pressure is
A person has to cover a distance of 6 km in 45 minutes. If he covers half of the distance in the remaining time, to cover the remaining distance in the remaining time, his speed must be
A person has to cover a distance of 6 km in 45 minutes. If he covers one-half of the distance in two-thirds of the total time; to cover the remaining distance in the remaining time, his speed(in Km/hr
