Answer:
the voltage drops will have the ratio 2 : 1
Explanation:
Assuming the loads have the same power factor, the voltage drop will be proportional to the load impedance. The loads have a ratio of 8 : 4 = 2 : 1, so the voltage drops will have a ratio of 2 : 1.
__
We assume the number associated with the load is representative of its impedance (not admittance, or some other measure).
Answer:
Explanation:
(a) Swirl tangential speed = 3 x MPS ( mean piston speed)
= 3 x 420.76 inch/sec = 280.51 [ft/sec]
The other detailed steps is as shown in the attached file
Answer:
Technician A
Explanation: Technician A is correct. Technician B is wrong, as an oil leak can trickle down onto other engine components, away from where the leak actually is.
Answer:
the pressure reading when connected a pressure gauge is 543.44 kPa
Explanation:
Given data
tank volume (V) = 400 L i.e 0.4 m³
temperature (T) = 25°C i.e. 25°C + 273 = 298 K
air mass (m) = 3 kg
atmospheric pressure = 98 kPa
To find out
pressure reading
Solution
we have find out pressure reading by gauge pressure
i.e. gauge pressure = absolute pressure - atmospheric pressure
first we find absolute pressure (p) by the ideal gas condition
i.e pV = mRT
p = mRT / V
p = ( 3 × 0.287 × 298 ) / 0.4
p = 641.44 kPa
so
gauge pressure = absolute pressure - atmospheric pressure
gauge pressure = 641.44 - 98
gauge pressure = 543.44 kPa
