6.4 (5) Draw the frequency domain circuit and calculate v(t) for the circuit shown if i(t)-10 sin(1000t -30°) A 35 Ω i(t) v(t) 15 mH 6.5 (5) Calculate the three phasor currents Ic, IR and It. from problem 6.4 and draw them on a phasor diagram. Show both algebraically and on the phasor diagram that: I=Ic + IR + IL
10 a) Plot a p(V) diagram containing a supercritical, the critical and a subcritical isotherm 6] for a material which exhibits van-der-Waals behaviour in the gaseous state. Mark the liquid, gaseous and supercritical regions and the critical point. b) Draw a p(V) curve of an ideal gas, either as a separate diagram on the same scale [2] as that in (a) or by making a clearly labelled addition to it. The plot should identify the position of the ideal gas...
5 Please sketch the following processes qualitatively on the P-v or T-v diagrams and calculate the change of internal energy of the process. Note: you need to have saturate line in your diagram and please write the numerical values of the initial state and final state on your diagram (a) T v diagram; water at the iniial state of 32 MPa and 30 C undergoesa (b) P- v diagram; water at the initial state of 2.5 bar and 0.6 quality...
Answer the following questions based on the v-t diagram for t = 0 - 10 seconds. What is the maximum velocity? When is the magnitude of the acceleration greatest? What is the acceleration at t = 2.4 s? At what time(s) is a = 0? Use the diagram to approximate the distance traveled between t = 1 and t = 3 seconds.
Draw a T-v diagram of a pure substance including the liquid, vapor, and liquid/vapor region. Using this diagram, explain what happens if a saturated liquid is heated (such that the temperature rises) in a rigid (constant volume) container. Using the same diagram, explain what happens when a saturated vapor is heated (such that the temperature rises) in a rigid container.
Represent in coordinates p-v and T-s the transformation for which a system receives heat but lowers its temperature. Explain why this is possible.
