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

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
