2 An analogue electrical indicating instrument has a moving coil of 4ohms resistance and gives full-scale deflection when carrying a current of 75mA. Explain, with the aid of sketches, how the instrument may be used to indicate at full-scale deflection of (i) a current of 10A and (ii) a P. D. of 100 V.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Plan an experiment to measure the surface tension of a liquid similar to water. if necessary, review the ncfmf video surface tension for ideas. which method would be most suitable for use in an undergraduate laboratory? what experimental precision could be expected?
