1. Superheated steam at 1000.°C and 1.00 MPa flows through a pipe located 20.0 m above the floor in a power plant with a velocity of 50.0 m/s. Determine the specific flow availability of the steam in the pipe when the local environment (ground state) is saturated liquid water at 20.0°C.
2. Saturated liquid ammonia at 0.00°C flows through a pipe located 10.0 m below the floor in a refrigeration system with a velocity of 3.30 m/s. Determine the specific flow availability of the ammonia in the pipe when the local environment (ground state) is saturated liquid ammonia at 0.00°C.
For a Wien-bridge oscillator (a) Given R = 50Kohm and C = 100nF what is the frequency of oscillation (b) Given a required frequency of oscillation of f = 10kHz and R = 8kohm, what should the value of C be
The maximum oven temperature to be maintained by the conventional type of thermostatic control is 290 degrees Celsius, the kitchen temperature may vary from 15 to 33 degrees Celsius, and the average heat transfer coefficient between the oven surfac..
Apply Coulomb's law to obtain an expression for the electric field at any point P (r, 0) on the x-y plane. Show that your result reduces to the expression given by Eq. (4.33) as the length L is extended to infinity.
a) Determine the closed-loop transfer function, T(s) = Output/Input = Y(s)/R(s) b)Find the time response, y(t) for a step input of r(t) = A for t>0 c)Using the final-value theorem, determine the steady-state value of the output y(t)
