d) Calculate the discharge coefficient, CD for an exhaust valve at a valve lift of 5 mm, if the exhaust airflow was measured experimentally to be 10 L/s at an upstream temperature of 57 C. The diameter of the exhaust valve is 25 mm. The pressure drop over the exhaust valve during the experimental measurement was measured at 250 centimeter of water with a manometer. R 287 J/kg, y = 1.4 and Patm = 1 bar.
