In a Carnot cycle, heat is supplied at 350°C and rejected at 27°C. The working fluid is water, which, while receiving heat, evaporates from liquid at 350°C to steam at 350°C. The associated entropy change is 1.44 kJ/kg K.a.If the cycle operates on a stationary mass of 1 kg of water, how much is the workdone per cycle, and how much is the heat supplied?b.If the cycle operates in steady flow with a power output of 20 kW, what is the steam flow rate?
Couette Flow Velocity Distribution, Using the log law, determine the velocity distribution for Couette flow between parallel plates a distance h apart, with U = the velocity of the top plate.
Evaluate the effect of the water spray on efficiency (net work out divided by heat input) and net power out per kg/s of dry air coming into the turbine.
Find the minimum power of the pump
Calculate the surface area available inside the heat exchanger.
Calculate the power required to overcome the skin friction drag on the keel of a sailing dingy moving through water at 2m/s. The keel projects 0.8m into the water and it is 0.4m wide
The airspeed of an aeroplane is measured with a Pitot tube. The plane is flying at an altitude of 10000m, and the Pitot tube measures a gauge pressure of p = 10kPa. What is the airspeed of the plane?
Complex loading (bending and compression), A steel chimney is 28m high, 1.4m external diameter, and 20mm thick. It is rigidly fixed at the base and is acted upon by a horizontal wind pressure of intensity 1.
