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?

taah

the answer is apparently F = −3.4xˆ +1.66yˆ kN but I am in need of the working please.

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?

that was potentially the most stupid question i have ever asked. thanks for your help sir.

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...
