How much energy is contained in a 40 meter wave? Also, are you assuming a perfectly square wave traveling at the arbitrary speed of 19.8 m/s? |

How much energy is contained in a 40 meter wave? See this site, which estimates that the southeast Asia tsunami had 0.5 terawatts total power – 1 gigawatt per kilometer of coastline. If the tsunami "lasted" a minute, that's about 7 kt. It also says that during the time the tsunami was only a meter high, it also traveled at 220 m/s and had a wavelength (i.e., in the direction of travel) of 300 km. |

How does cooling scale with volume? @Georg, vaporization and convection are both rolled up into the heat transfer coefficient. True, I assume that h is constant with temperature, but generally people aren't so anal about obvious back-of-the-envelope calculations. What's with the chip on your shoulder? |

Figuring out the force using Newton's 2nd Law Working from $F\cos(-30°)=\mu_sF_N=0.4\left[9.807\times 12-F\sin(-30°)\right]$ gives $F=70.7$. Check your math. |

2 streams going into an engine and 2 come out. Find the enthalpy? Oh. Nevermind, then. But if you have two streams coming in at .01 kg/s, you can't have an exit stream at .109 kg/s. |

2 streams going into an engine and 2 come out. Find the enthalpy? You seem to have made some typos in the question, but my first guess anyways is that you've made a mistake with the units on $\tfrac{v^2}{2}$: $1 \tfrac{\text{m}^2}{\text{s}^2}$=1 J/kg, so if you add it to enthalpies in kJ/kg you'll get a greater outlet enthalpy. |
