A steam turbine is operating at a steady state with a mass flow rate of 3682 kg/h at the inlet. The power output of the turbine is 8700 kW. Steam enters the turbine at a pressure of 40 bar, temperature of 320 oC, and with a velocity of 13 m/s. The exit conditions from the turbine are characterized by a pressure of 0.1 bar and the quality 90% with the velocity of 27 m/s. Determine the heat transfer rate between the turbine and surroundings, in kW.
A horizontal cantilever of length L supports a load W, uniformly distributed along its length. the cantilever is proped to the level of the fixed end at a distance 3/4 L from that end. Determine the load on the prop.
A particle travels around a circular path having a radius of 66m. It is initially traveling with a speed of 10 m / s and its speed then increases at a rate of v = (0.05v) m /s2. Determine the magnitude of the particle's acceleration four seconds late..
