The table shows the masses of four objects. A 2-column table with 4 rows. The first column labeled object has entries book, rock, box, fish. The second column labeled mass (kilograms) has entries 1.1, 2.3, 4.5, 5.8.

Which object has a weight of about 22.5 N?

the book
the rock
the box
the fish

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%)
