The speed of sound v in air is approximately 331.4 m/s + 0.6T The speed of light c is 300, 000 km/sec which means it travels from one place to another on Earth more or less instantaneously . Let's say on a cool night (air temperature 10° Celsius ) you see lightning flash and then hear the thunder rumble five seconds later . How far away in km) did the lightning strike ?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
