All four tubes in the image below have the same driving pressure gradient. Based on this and their dimensions you know tube ________ has the greatest flow and tube _____has the least flow per unit time.

The IV system shown below contains whole blood at a height of 0.857 m. Determine the gauge pressure (in psi) at the injection point [round your final answer to two decimal place]. 1 atm= 14.7 psi 1 atm = 1.013x105 Pa I atm = 760 mmHg h Density of whole blood = 1,060 kg/m³

Water flows through a horizontal pipe at a rate of 2.4gal/s. The pipe consists of two sections of diameters 4 inch and 2 inch with a smooth reducing section. The pressure difference between the two pipe sections is measured by a mercury manometer. Neglecting frictional effects, determine the differential height of mercury between the two pipe sections. The answer is 3.0 inches Please show all steps

I didn't answer any of it I just pulled the list down so you can see the different options.

An incompressible fluid is flowing from left to right in the horizontal pipe shown. The diameter varies through this section of piping. At which of the points shown, labeled A through E, does the mass flow rate have greatest value? A O O O O O O с B B C The mass flow rate has the same value at all of the positions shown. A D E
