Please synthesize a four bar linkage that produces a kidney bean shaped coupler curve (or as close as possible) using the Hrones and Nelson atlas.
A) Please list all the link lengths assuming crank length 0.5 m.
B) Indicate the shape of the coupler link and identify the coupler point.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
