One kilogram of water in a frictionless piston-cylinder assembly undergoes an internally reversible, isentropic transformation from t_1 = 10 degree c, p_1 = 0.1mpa to t_2 = 90 degree c, and p_2 = 0.5 mpa. consider water as incompressible substance with constant specific heat, c = 4.211 kj/kg. k. assume that no phase transitions occur. determine: the heat transfer and the work for the process; the total entropy variation and entropy generation during the process.

are their multiple choices ?

explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
