A fan has a bladed rotor of 30 cm outside diameter and 12 cm inside diameter and turns at rate ω = 180 rad/s. The width of each rotor blade is 2.7 cm and the volume flow rate is Q = 0.1 m3 /s. The absolute velocity of the air (rho = 1.23 kg/m3 ) at blade inlet, V1, is purely radial. What would be a reasonable blade inlet angle (measured with respect to the tangential direction at the inside diameter of the rotor)?

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
