Steam Boilers, Engines, Nozzles and Turbines A throttle governed steam engine develops 15 kW with 280 kg per hour of steam and 35 kW with 520 kg per hour of steam. The steam consumption in kg per hour when developing 20 kW will be nearly 210 kg/h 150 kg/h 340 kg/h 280 kg/h 210 kg/h 150 kg/h 340 kg/h 280 kg/h ANSWER DOWNLOAD EXAMIANS APP
