6 Two cyclists, A and B, have displacements 0 km and 70 km, respectively. At t=0 they

begin to cycle towards each other with

velocities 15 km h and 20 km h-',

respectively. At the same time, a fly that was

sitting on A starts flying towards B with a

velocity of 30 km h-'. As soon as the fly

reaches B it immediately turns around and

flies towards A, and so on until A and B meet.

(a) What will the displacement of the two

cyclists and the fly be when all three

meet?

(b) What will be the distance travelled by the

fly?

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.
