Homework Statement The 40 kg crate shown in the Figure below rests on a horizontal plane for which the coefficient of kinetic friction is mk = 0.3. If the crate is subjected to a 350 N towing force as shown, determine the speed of the crate 3 seconds after starting from rest. + given angle of...

Ok thank you.

Hello, My knowledge on fluid mechanics is on a introductory level. When explaining, it would be great if you could explain in simple English and also like teaching to a student who isn't very good at the subject area! I've been reading a lecture slide and have been trying to follow the example...

Ok thank you for clear the explanation! Ok thank you! Ah I see thanks! Yes, it looked like my calculated pressure was too small. Ok thank you! I'll try it again. Thank you very much paisiello2, SteamKing, BvU and Chestermiller for your responses!

Homework Statement A circular viewing window of diameter D = 0.4m is placed in the Holding tank. The top of the window is H = 1.2m below the water surface. Find the hydrostatic force acting on the window and locate the corresponding centre of pressure (CP). There is a diagram attached to the...

Ok thank you for your help! I appreciate it.

Thank you very much again. I tried the problem again earlier, it's a bit long though: ---- $$ N_R = V D \rho/μ$$ Where, N_R = Reynolds number V = Velocity of flow, 0.4947m/s D = Diameter of pipe, 0.35m ρ = Density of water at 20°C, 998 kg/m^3 μ = Dynamic Viscosity, 1x10^-3 Pa*s...

Thank you for your response. Oh ok so head is just another name for pressure. I see.No, how do I determine if a flow is laminar? I was reading a webpage saying that laminar flow is 'smooth' and 'turbulent' flow is 'rough'. Is this description true? http://en.wikipedia.org/wiki/Laminar_flow...

Hello. I have had an attempt at solving this pressure drop problem, but I have been told it is incorrect. I am very much a beginner in the area of fluid mechanics, so if you could please define any terms that you are using, that would be so helpful! I thought using the Hagen-Poiseuille would...
