yea this is right. it can be basically thought of as a converging pipe and the question is based on the internal volume as this helpful fella said. and the mass is the mass of the actual reducer.
i have obtained the answer but not confident on my methods. anyone else had any luck?
Homework Statement
The internal volume of the reducer is 0.2m^3 and its mass is 25 kg. The fluid being pumped is oil (specific gravity of 0.72).
Evaluate the total force that must be provided to support the reducer.
d1 = 0.4m
d2 = 0.2m
u1 = 3m/s
p1 = 58.7 kPa
p2 = 49kPa (gauge)...
Homework Statement
A solid sphere - 20mm in diameter, σ (specific gravity) = 1.3
dropped in water μ=1*10^-3 and ρ=1000
determine the terminal velocity for the sphere.
(hint- guess the value for the drag coefficient then iterate)
Homework Equations
Fd=(1/2)*Cd*ρ*(U^2)*A...
What are the relationships between these 3 properties of a fluid and how would you calculate say the density when you know the viscosity and specific gravity?
A television transmitting antenna is placed on top of a mast which is 30m high and 300mm in diameter. The mast is on top of a tall building. The wind blows at 35m/s and at normal atmospheric pressure (1.225kg/m^3). If the drag coefficient for the mast is 0.2. calculate:
(i) the total drag...
