The two loads in Figure 5 can be described as follows: Load 1 absorbs an average power
of 6 kW at a leading power factor of 0.7. Load 2 absorbs 18 kVA at a lagging power
factor of 0.55. Determine the following.
The real, net reactive and apparent power of each load.
Draw the power triangle for each load.
111)The current through each load
iv)The total apparent power of both loads.
v) The total current
vii) The resultant power factor of the two loads.
vii)
The power rating of the 0.05 N resistor.
viii) Given that power sources operates at 50Hz find the capacitance required to correct the power factor to a value of 1

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
