Oand o' have parallel axes. according to o, o' is moving with velocity, v = (vi , v2, v3) = ! v! (sin a cos b, sin a sin b, cos a) what is the lorentz transform, χμ'v', between these reference frames? what is the relationship between, a.μ.v, and xv.μ? prove that the proper time, eq. (1.8), is an invariant. if o looks at a rod that formally had rest length, l, that now is aligned with the velocity vector and moving with velocity, v, what will o consider the length to be? do this problem as follows: find the rotation that takes o' to o" such that, ês, is aligned with, v. then apply the lorentz tranform this takes you to system o, where o is obtained from o by the same rotation that took o' to o". now apply the inverse rotation to get from o to o.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
