What must the Hubble constant be if the Universe is flat. At the Lamda CDM article on wiki it says 70.4 km/s mpc. I'm not sure if that's what it must be if the universe is flat or if that's what experiments have measured it to be, I'm 99% sure that it's the former but I want to be 100% sure. Also I've read the wiki article on the Hubble constant and all the various experiments that have been done to measure it so you don't need to tell me that.
