The small boat show in in the figure is driven at a steady speed vo by a jet of compressed air issuing from a 3-cm-diameter hole at Ve= 250 m/s. Jet exit conditions are Pe = 1 atm and Te= 30°C. Therefor, the air density is Pe /R Te =1.165 kg/m³. Air drag is negligible, and the hull drag is k.Vo2 , where k = 19 N · s2/m2 . Estimate the boat speed Vo in m/s. D;= 3 cm Compressed V -E air Vo Hull drag kV P3.48

please help me.

The small boat show in in the figure is driven at a steady speed Vo by a jet of compressed air issuing from a 3-cm-diameter hole at Ve = 250 m/s. Jet exit conditions are Pe = 1 atm and Te = 30°C. Therefor, the air density is Pe /R Te 1.165 kg/m3. Air drag is negligible, and the hull drag is k. Vo2 , where k 19 N• s2/m2 . Estimate the boat speed Vọ in m/s. D,= 3 cm Compressed V -E air Vo Hull drag kV P3.48 Vo=2.32 m/s Vo=1.33 m/s Vo=1.99 m/s Vo=1.66 m/s
