Question

The small boat in the figure given below is driven at a steady speed $V_0$ by a jet of compressed air issuing from a 12-cm-diameter hole at $V_e = 343$ m/s . Jet exit conditions are $p_e = 1$ atm and $T_e = 30^\circ$C . Air drag is negligible, and the hull drag is $kV_0^2$, where $k \approx 19$ N $\bullet$ s$^2$/m$^2$ . The air density is 1.165 kg/m$^3$ . Estimate the boat speed $V_0$ in m/s. Compressed air $V_e$ $V_0$ Hull drag $kV_0^2$ The boat speed $V_0$ is m/s.

Step 1

12 m - Jet exit pressure, $p_e = 1$ atm = 101325 Pa - Jet exit temperature, $T_e = 30^\circ$C = 303.15 K - Hull drag coefficient, $k = 19$ N $\bullet$ s$^2$/m$^2$ - Air density, $\rho_{air} = 1.165$ kg/m$^3$ (This is given as the air density, but it's important to Show more…
