When fluid is in static equilibrium it obeys ___________ That is, it is only under compressive forces and those forces act with equal intensity in all directions at any point in the fluid.
The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: A single device can heat fluids without requiring an electrical element. S6: Because there is no electrical element, there is no risk of fire, so the system is suitable for dangerous environments. P: A heat exchanger transfers heat from the central cavity to an air heater, a water heater or an industrial processor. Q: It has a container like the crankcase of a car’s engine, which contains the fluid to be heated. R: Compression and friction at the nozzles heat the fluid so that the temperature in the central -cavity rises steadily. S: A motor and pulley inside the container turn a rotor wheel, which in turn forces the fluid again and again through narrow nozzles into a central cavity. The proper sequence should be
The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: The imposition of Governor’s rule in Jammu and Kashmir will not affect operations in the state, according to Army Chief General, even as security forces are looking at higher intensity of operations against terrorists, to force them to ‘hibernate’. These operations will be based on greater level of intelligence from the J&K Police, as compared to what was being generated during the suspension of operations for the holy month of Ramzan. A challenge, however, for the security forces still remains the recruitment of local terrorists. Why? Arguments: I. Meanwhile, data shared by security forces reveal that there are about 210 terrorists currently operating in Kashmir, mainly in the South. Out of this, 65 per cent are locals and the remaining are foreign terrorists.  II. In South Kashmir itself, the maximum number of terrorists belong to the HizbulMujahideen, while some are from the Lashkar-e-Toiba and Jaish-e-Mohammed. III. When a local terrorist is killed during an operation, at his funeral more locals are willing to join terrorism. It is a mob mentality.
For turbulent flow (NRe > 2100) of low viscosity fluid (μ > 20cp) in steel pipes, the optimum inside pipe diameter is given by (where, Q = fluid flow rate, ft3/sec.ρ = fluid density, lb/ft3.μ = fluid viscosity, centipoise Di = optimum inside pipe diameter, inches)
