All objects have mass. Mass is the amount of material in an object, usually measured by its weight. Earlier in this unit, you studied the volume of objects. When you combine these two concepts, you get a useful measurement called density. The density of an object is its mass per unit of volume. Imagine two objects in which the larger one actually weighs less than the smaller one. This difference in weight is attributed to density. Consider a candle that has a volume of 96 cubic inches and a weight of 44.16 ounces. What is the density of the candle

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%)
