A 100KW, 250 V, 400 A, a long shunt compound generator has an armature resistance of 0.025 ohms. There are 1000 shunt fields turns per pole and 3 series field turns per pole. The series field is connected in a such a fashion that positive armature current produces direct-axis MMF which adds to that of the shunt field. Compute the gross MMF at the rated terminal current when shunt field current is 4.7A and speed is 1150 rpm.
Six boxes containing different items namely, Copy, Pen, pencil, Scissor, Tape and Paper, are kept in a straight line, one after the other, not necessarily in the same order. The box of Pen is kept at the third position in the line from the left end. The box of Paper is kept at the extreme right end. The box of Pencil is kept somewhere between box of pen and box of paper. The box of Tape is kept at the left of the box of Pen but at the right of the box of Copy, when counting from the left end. The box of scissor is not kept immediately next to Paper. Which box is kept at the second position from the right end?
Thomas filled the tank through three pipes X, Y and Z. Pipe X is kept open in continuation, pipe Y kept open for first 20 minutes and then he closed it. 5 minutes after pipe B was closed, Pipe C is opened and was kept open till the tank was full. Together all the 3 pipes X, Y and Z take 'a' minutes to fill the tank. Each pipe fills an equal share of the tank. also, it is known that if pipe X and Y are kept open throughout, the tank would be completely fill in 'a' minutes. How long will it take C alone to fill the tank?

The handle of a saucepan, 30 cm long and 2 cm in diameter, is subjected to 100 degree Celsius temperature during a certain cooking operation. The average unit surface conductance over the handle surface is 7.35 W/m2 degree in the kitchen air at 24 degree Celsius. The cook is likely to grasp the last 10 cm of the handle and hence the temperature in this region should not exceed 38 degree Celsius. What should be the thermal conductivity of the handle material to accomplish it? The handle may be treated as a fin insulated at the tip
A container of 425 liters was filled with chemicals through two pipes. The first pipe was kept open for 5 hours more than the second pipe. If the first pipe remains open for as long as the second pipe remains open, and the second pipe remains open for as long as the first pipe remains open, then the quantity of chemical filled by the first pipe was half the quantity of chemical filled by the second pipe. If both the pipes are opened simultaneously, the tank will be filled in 17 hours. For how long was the second pipe open?
