Answer:
1.1775 x 10^-3 m^3 /s
Explanation:
viscosity, η = 0.250 Ns/m^2
radius, r = 5 mm = 5 x 10^-3 m
length, l = 25 cm = 0.25 m
Pressure, P = 300 kPa = 300000 Pa
According to the Poisuellie's formula
Volume flow per unit time is
V = 1.1775 x 10^-3 m^3 /s
Thus, the volume of oil flowing per second is 1.1775 x 10^-3 m^3 /s.
Answer:
0.5 m
14.00595
8 m/s, 0.0625 s
5.71314 m/s
Explanation:
k = Spring constant = 128 N/m
A = Amplitude
E = Energy in spring = 16 J
Energy in spring is given by
The amplitude is 0.5 m
Time period is given by
Number of oscillations is given by
The number of oscillations is 14.00595
For maximum speed
The maximum speed is 8 m/s
For a distance of 0.5 m which is the amplitude
The time taken would be 0.0625 s
The maximum kinetic energy is equal to the mechanical energy
At x = 0.35 m
The speed of the block is 5.71314 m/s
