What is the push provided by a hydraulic fluid used in fluid based actuator, if a steel ball of radius 3cm is immersed in it, Given that the fluid has a density of 1200kg/m3, Take g=10m/s2? Correct Answer 1.356N

GiveDensity of fluid (ρf) = 1200kg/m3 g=10m/s2 Radius=3cm Volume of steel ball (V) = 4/3πr3=4/3π (0.03 m)3 V=1.13*10-4 m3 Push (P) = ρf*g*v P=1200kg/m3*10m/s*1.13*10-4 m3 P=1.356N

A steel ball (density ρsteel = 7200 kg/m3) is placed in an upward moving liquid AI (density ρal = 2360 kg/m3, viscosity μAl = 1 × 10-3 Pa.s and Reynolds number = 5 × 105). The force (F) exerted on the steel ball is expressed as F = fπR2(ρAl V2/2)
where, f is friction factor (= 0.2), v is the velocity of liquid AI and R is the radius of steel ball.
The force exerted on the steel ball is
