the conductor (CL) can slide without friction on the vertical conductors which are made of insulated material. The mass of the conductor is m = 200gr the length of l = 1m the intensity of the gravitational field g = 10 m / s ^ 2, while the intensity of the homogeneous magnetic field B = 0.1T Calculate the current intensity and the direction in KA pipeline so that: a) the pipeline is rising at a constant speed, b) the pipeline rises with a constant acceleration a = 2 m / s ^ 2 c) the pipeline descends at a constant speed; d) the pipeline descends with constant acceleration a = 12 m / s. 2.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.

What’s #16 asking and how do i solve it?

Ascientific blank must be testable and capable of being proven false?
