1. A hot-wire anemometer comprising electrical resistance bridge means including a fiber hot wire resistor in one arm thereof that has a temperature-dependent resistance, said fiber hot wire being formed substantially of graphite, means for supplying electrical power to said fiber hot wire to internally heat the same, means for supporting a span of said hot wire in tension for exposure to a stream of flowing cooling gas, and signal converting means coupled to said bridge means for correlating the cooling effect on the hot wire resistance with gas flow velocity.
