Answer:
The correct option is;
A. be in compliance with school attendance requirements
Explanation:
The requirements to acquire a special restricted driver's license for driver's license for under under 18 that have had a beginner's for up to 180 days include a minimum of 40 hours driving practice 10 of which should be in the dark. The application for the conditional drivers license is to be signed by the parent or guardian and the application is to be accompanied with proof of acceptable school attendance
At 17, after holding the special restricted drivers licence for a year without issues you can obtain the full drivers license.
Answer:d
Explanation:
Given
Temperature![=200^{\circ}\approc 473 K](https://tex.z-dn.net/?f=%3D200%5E%7B%5Ccirc%7D%5Capproc%20473%20K)
Also ![\gamma for air=1.4](https://tex.z-dn.net/?f=%5Cgamma%20for%20air%3D1.4)
R=287 J/kg
Flow will be In-compressible when Mach no.<0.32
Mach no.![=\frac{V}{\sqrt{\gamma RT}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BV%7D%7B%5Csqrt%7B%5Cgamma%20RT%7D%7D)
(a)![1000 km/h\approx 277.78 m/s](https://tex.z-dn.net/?f=1000%20km%2Fh%5Capprox%20277.78%20m%2Fs)
Mach no.![=\frac{277.78}{\sqrt{1.4\times 287\times 473}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B277.78%7D%7B%5Csqrt%7B1.4%5Ctimes%20287%5Ctimes%20473%7D%7D)
Mach no.=0.63
(b)![500 km/h\approx 138.89 m/s](https://tex.z-dn.net/?f=500%20km%2Fh%5Capprox%20138.89%20m%2Fs)
Mach no.![=\frac{138.89}{\sqrt{1.4\times 287\times 473}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B138.89%7D%7B%5Csqrt%7B1.4%5Ctimes%20287%5Ctimes%20473%7D%7D)
Mach no.=0.31
(c)![2000 km/h\approx 555.55 m/s](https://tex.z-dn.net/?f=2000%20km%2Fh%5Capprox%20555.55%20m%2Fs)
Mach no.![=\frac{555.55}{\sqrt{1.4\times 287\times 473}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B555.55%7D%7B%5Csqrt%7B1.4%5Ctimes%20287%5Ctimes%20473%7D%7D)
Mach no.=1.27
(d)![200 km/h\approx 55.55 m/s](https://tex.z-dn.net/?f=200%20km%2Fh%5Capprox%2055.55%20m%2Fs)
Mach no.![=\frac{55.55}{\sqrt{1.4\times 287\times 473}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B55.55%7D%7B%5Csqrt%7B1.4%5Ctimes%20287%5Ctimes%20473%7D%7D)
Mach no.=0.127
From above results it is clear that for Flow at velocity 200 km/h ,it will be incompressible.
Answer:
P=11 kW
Explanation:
Given that
Number of poles= 8
I.E.C. 180L motor frame
From data book , for 8 poles motor at 50 Hz
Speed = 730 rpm
Power factor = 0.75
Efficiency at 100 % load= 89.3 %
Efficiency at 50 % load= 89.1 %
Output power = 11 kW
Therefore the rated output power of 8 poles motor will be 11 kW. Thus the answer will be 11 kW.
P=11 kW
