(3) For a fluid undergoing steady rotational flow at low Reynolds number with angular velocity w in acylindrical polar co-ordinate system (r, 0, z), we find3 r. (~² dw)rər= 0.(a) Find an expression for a (include two constants of integration) and use it to identify twotypes of steady circular motion.(b) Find the magnitude of the vorticity in terms of @ for each of the two cases. You may wishto use the formula for curl in cylindrical polar co-ordinates when there is no variation in the zdirection,1VAU= = ( 3 (rus) _rdurae2.

A rectangular solid made of aluminum has a density p= 2.70 g/cm³. The dimensions of the solid are shown below. The solid is placed on top of a truncated cone whose circular ends have the dimensions shown. The bottom of the rectangular solid down on the top surface of the cone. Find the pressure (in N/m²)between those two surfaces. (Ignore air pressure.) (1 kg = 1000 g, 1 m 100 cm) presses 10.0 cm 8.00 cm 15.0 cm r= 2.00 cm R = 6.00 cm
Question 1 a) Consider the forces acting on an infinitesimal fluid element located at radius r inside a star, where the star is in hydrostatic equilibrium. Show that the buoyancy force acting on the fluid element may be written as Pe dv dt = -(Pe - p)g where Pe is the density inside the fluid element, p is the density of the gas in the surrounding gas at radius r, v is the velocity of the fluid element and g is local acceleration due to gravity. For full marks you should explain each step of your derivation. b) With the aid of a diagram, explain the condition required for convection to occur by considering the small displacement of a fluid element from its original equilibrium location within a star.
Calculate the gauge pressure (in Pa first, then convert) due to whole blood in an IV system such as the one shown in picture below if h = 2.03 m. b) Noting that there is an open tube, so that atmospheric pressure is exerted on the whole blood in the bottle, calculate the total pressure (absolute) exerted at the needle by the blood. Report both answers in mm of Hg.(1 atm= 14.7psi = 1.013x105 Pa= 760 mmHg; Absolute)(Density of whole blood = 1060 kg/m3)
