2.15. The fern is defined as the unit of force required to accelerate a unit of mass, called the bung, with the gravitational acceleration on the surface of the moon, which is one-sixth of the normal gravitational
acceleration on earth.
(a) What is the conversion factor that would be used to convert a force from the natural unit to the
derived unit in this system? (Give both its numerical value and its units.)
(b) What is the weight in ferns of a 3-bung object on the moon? What does the same object weigh
in Lizard Lick, North Carolina?​

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.
