Consider lifting potential flow around a spinning circular cylinder of radius r put in uniform flow with a velocity magnitude ofv[infinity]. if the circulation around the cylinder is γ = 2πv[infinity]r, (a)find the locations of the stagnation points, (b) determine and plot (with computer) the pressure coefficient distribution on the surface of the cylinder, and (c) calculate the lift and the drag coefficients.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.

What happens when the vapor pressure of a liquid is equal to the external pressure?

If the pressure in a gas is doubled while its volume is held constant. true or false
