use the Lee-Kesler generalized charts

Problem 6 Ethane at 63C and 2.44MPa is compressed isothermally and reversibly in a steady flow compressor to a pressure of 15MPa at a flow rate of 3kg/s. During this process, an amount of q =350kJ/kg heat is transferred to the surrounding at 25C. Using the generalized charts answer the following: (a) Determine the total entropy generated in this process, in kW/K, (b) Determine the power input of the compressor, in kW, (c) Determine the diameter of the compressor exit in cm if you want have a velocity of 10m/s at this stream
