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 in the axial direction. The temperature at a distance 100 mm from the dipped end becomes 40°C at time, t = 200 s. The same temperature is achieved at a distance of 200 mm from the dipped end at time
Consider the following statements regarding precision in measurements of a quantity: 1. Precision is the measure of the spread of the incident errors. 2. Precision is independent of the realizable correctness of the measurement. 3. Precision is usually described in terms of number of digits used in the measurement by a digital instrument. Which of the above statements are correct?
When a pattern is to be withdrawn from the mould, it is first shaken, by striking over it from side to side, so that its surface may be free of the adjoining sand wall of the mould. That causes the size of the mould cavity increases a little and a negative allowance is to be provided in the pattern to compensate the same, is known as:
A 250 mm by 250 mm ingot casting, 1.5 m high and at 1225 K temperature, is stripped from its mold. The casting is made to stand on end on the floor of a large foundry whose wall, floor and roof can be assumed to be at 300 K temperature. Make calculation for the rate of radiant heat interchange between the casting and the room. The casting material has an emissivity of 0.85
At the mould exit of a continuous caster, the metal consisting of a solidified shell with a liquid metal core exits at the rate of 35 kg S-1. Given that the latent heat of fusion is 3 × 105 J kg-1 and the total rate of heat removal by the mould is 4.2 × 106 W, the mass fraction of solid at the mould exit is . . . . . . . .
Assume that both while solid and liquid remain at the melting point, they are in the mould.

Rajesh along with Reena accepted the order to prepare x number of dresses. For the order, 44.44% of the material is prepared by Reena and rest is prepared by Rajesh. It is found that 14.29% of dress prepared by Reena is defective and for Rajesh, the number is 16.67%. If one of the dresses had been picked up from the bunch, what is the probability that it is prepared by Rajesh and it is in good condition?
