Water at 2.5 Mpa and 200Β°C is heated at constant temperature up to a
quality of 80%. Find (a) the quantity of heat received by the water, (b) the
change in internal energy, and (c) the work of nonflow process. (HINT:
table 4 needed)
Five kg of water vapour are contained at 150 kPa ad 90 per cent quality in a
suitable enclosure. Calculate the heat which must be added in order to just
produce a saturated vapor. What will the pressure be at the end of the
heating process?
5.A 10 kW, 400 V, 4 pole delta-connected squirrel cage induction motor gave the following test results:

The non-zero and finite steady state error for the appropriate input depending on the system type. c. If the damping ratio is to be made to 0.75 from the original value obtained in 2 (a) using a tachometer feedback, calculate the tachometer constant πΎπ‘ and determine the percentage overshoot then
A single DOF model of a vehicle suspension system is shown in Fig. 1. The vehicle is
travelling over a rough road with a horizontal velocity of π m/sec. The road contour is
approximated by a sinusoid with a wavelength of 2 m and an amplitude of 3 mm. The
mass of the vehicle is 1500 kg. The equivalent spring constant of the suspension
system is 3 Γ 107 N/m and the system has a frictional coefficient of 1.5 Γ 105 N-s/m.
a. Write an expression for βyβ as a function of π and time.
b. If π = ππ π/π, what is the maximum displacement and acceleration of the
body of the vehicle? Also add a matlab plot for this condition (input
displacement βyβ vs time and output displacement βxβ vs time on a single plot
with legend)
c. For what values of π in m/s will the maximum displacement of the body be
limited to 4.5 mm?
d. For what value of π the maximum displacement will be maximum? Find the
maximum displacement for that π£.
