Asimple ideal brayton cycle uses argon as the working fluid. at the beginning of the compression, p1 = 15 psia and t1 = 70°f, the maximum cycle temperature is 1220°f, and the pressure in the combustion chamber is 150 psia. the argon enters the compressor through a 3 ft2 opening with a velocity of 200 ft/s. determine the rate at which entropy is generated by the cycle. the temperature of the source is the same as the maximum cycle temperature, and the temperature of the sink is the same as the minimum cycle temperature.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the device is called “ rocket engine”

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
