How does 'Spain 1936' present the revolution of Asturias in October 1934? Like a 'popular movement' repressed by the right. Like a violent revolutionary movement against democracy organized by communists and socialists. Like an anti-bourgeois revolution that took the lives of hundreds of innocent people. Like a violent movement organized by the right-wing government that was in power in Spain at the time.

Tutorial EG501V Computational Fluid Dynamics (2017/18) Tutorial 7. Turbulence 23 October, 4-5 pm in FN2 (Q1) The mechanical energy per unit time (i.e. power $P$) needed to maintain a flow in a pipe relates to the volumetric flow rate $\phi_v$ and the pressure drop $\Delta p$ over the pipe: $P = \phi_v \Delta p$. The pressure drop relates to the average velocity $U = \frac{\phi_v}{\pi D^2/4}$ in the pipe ($D$ is the pipe diameter) according to $\Delta p = 4 f \frac{L}{D} \rho U^2$ with $L$ the length of the pipe and $f$ the Fanning friction factor. The latter depends on the Reynolds number and the roughness of the pipe's inner surface. Here, however, we take $f$ as a constant: $f=0.01$. For a pipe with $D=2.5$ cm and a volumetric flow rate of $\phi_v = 20$ litre/minute, estimate the size of the smallest eddies (Kolmogorov eddies) if the working liquid is a silicon oil with $\rho = 950$ kg/m$^3$ and $\mu = 1.8 \cdot 10^{-3}$ Pa's.
3.80 - Finding Velocity and Displacement from Acceleration Points: 20 The velocity of a particle moving along the x-axis varies with time according to $v(t) = A + Bt^{-1}$, where A = 1.70 m/s, B = 0.260 m, and 1.0 s ? t ? 8.0 s. Determine the acceleration and position of the particle at t = 1.7 s and t = 5.7 s. Assume that x = 0 m at t = 1.0 s. Att t = 1.7 s: (acceleration) (position) Submit Answer Tries 0/100 Att t = 5.7 s: (acceleration) (position) Submit Answer Tries 0/100
