(Science-Ncert class 6)1 AnswerA tester is used to check the conduction of electricity through two liquids, labelled A and B. It is found that the bulb of the tester glows brightly for liquid A while it glows very dimly for liquid B. You would conclude that cbse-class8-physics-20151 AnswerA calorically perfect gas (specific heat at constant pressure 1000 J/kg.K) enters and leaves a gas turbine with the same velocity. The temperatures of the gas at turbine entry and exit are 1100 K and 400 K, respectively. The power produced is 4.6 MW and heat escapes at the rate of 300 kJ/s through the turbine casing. The mass flow rate of the gas (in kg/s) through the turbine is1 AnswerThe stagnation temperatures at the inlet and exit of a combustion chamber are 600 K and 1200 K, respectively GATE-Aerospace Engineering-Question-20121 AnswerA thick coating of a paste of Plaster of Paris (POP) is applied over the bandage on a fractured bone. It becomes hard on drying to keep the fractured bone immobilised. Can the change in POP be reversed? (Science-Ncert class 6)1 Answer
