Calculate the retarding force due to the viscosity of the air layer between a cart and a level air track given the following information—air temperature is 20º C , the cart is moving at 0.400 m/s, its surface area is 2.50×10−2 m 2 , and the thickness of the air layer is 6.00×10−5 m . A) 0.00302 N B) 0.00156 N C) 0.0103 N D) 0.00604 N
86. Calculate the Reynolds numbers for the flow of water through (a) a nozzle with a radius of 0.250 cm and (b) a garden hose with a radius of 0.900 cm, when the nozzle is attached to the hose. The flow rate through hose and nozzle is 0.500 L/s. Can the flow in either possibly be laminar? 62. (a) Calculate the retarding force due to the viscosity of the air layer between a cart and a level air track given...
63. What force is needed to pull one microscope slide over another at a speed of 1.00 cm/s, if there is a 0.500-mm-thick layer of 20° C water between them and the contact area is 8.00cm2? 64. A glucose solution being administered Wth an IV has a flow rate of. What will the new flow rate be if the glucose iseped by whole blood having the same density but a viscosity 2.50 times that of the glucose? All other factors...
5. What force is needed to pull one microscope slide over another at a speed of 1.00 cm/s, if there is a 0.500-mm-thick layer of 20 degrees C water between them and the contact area is 8.50 cm^2?
A 300 W immersion heater is used to heat 400 g of water from 10 ⁰C to 80 ⁰C. About how many minutes did this take? 5 min 3.5 min 2 min None of the above is correct As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed increases by a factor of 4.00 and the total cross-sectional area of the venules is 9.5 cm2, what is the...
