Refrigerant 134a enters a well-insulated nozzle at 200 lbf/in.2, 200°f, with a velocity of 120 ft/s and exits at 50 lbf/in.2 with a velocity of 1500 ft/s. for steady-state operation, and neglecting potential energy effects, determine the temperature, in °f, and the quality of the refrigerant at the exit.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

attach the statements so i can answer : )

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
