Question 5) In the system shown in the figure, atmospheric air is sucked from the section 1 with a compressor with a pressure of 5,ab bar. 25% of the sucked air from tank A is delivered to turbine after passing a nozzle., inlet and outlet diameters of a nozzle having 10ab mm long are 2abmm and 1abmm respectively; And then the air leaving the turbine is discharged into the atmosphere with a very short pipe with a diameter of 1abmm and 10ab m long. Take the absolute pressure in tank A is 5,ab bar, find the power of the turbine and the electrical energy generated by the generator for 3a, b % of the total efficiency. the pipes used in the system are made of galvanized pipes (roughness value ε = 0.15mm). Solve the problem by making the necessary assumptions and drawing the schematic figure. Minor loss coefficients are K1=0,5ab, K2=K4=1.ab, and K3 will be calculated.
here, d1 and d2 are inlet and outlet of the nozzle.
