// Solution

//The velocity of sound in air at 1000 F is
Va=49.0*sqrt(T); //velocity //ft/s

//Hydrogen has a specific heat ratio of 1.41 and R=766.53.Therefore,

// Vahydrogen/Vaair = sqrt((Rhydrogen*khydrogen)/(Rair*kair))
//rearranging,
Vahydrogen=Va*sqrt((Rhydrogen*khydrogen)/(Rair*kair)); //The velocity of sound in hydrogen at 1000 F //unit:ft/s
