Certain geological features of this planet produce a gas that changes the radius of blood vessels by 5% at the time of inhalation. What would the corresponding increase in blood flow through the vessel at this time be? Write 1-2 sentences explaining how you found your answer.Write T as an answer if the statement is true and F as an answer if the statement is wrong. If your answer is F, then correct the statement Example: Q1- Sinop is a southern city located at Anatolia. A typical answer 1- F: Sinop is a northern city located at Anatolia. Question2-1 Thermal hot wire anemometers measure the temperature of the flow, and they are very small devices which do not disturb the flow significantly.

- Mechanical engineering thermodynamics. Handwritten solution accepted. (3-150) In an article on tire maintenance, it is stated that tires lose air over time, and pressure losses as high as 90 kPa (13 psi) per year are measured. The article recommends checking tire pressure at least once a month to avoid low tire pressure that hurts fuel efficiency and causes uneven thread wear on tires. Taking the beginning tire pressure to be 220 kPa (gage) and the atmospheric pressure to be 100 kPa, determine the fraction of air that can be lost from a tire per year.Question 4 Viscosity.

- Which of the following is an incorrect way of measuring the volume of liquids from volumetric glassware? Tilt the volumetric glassware to position your line of sight to the bottom of the liquid's meniscus. Record the volume of a liquid in volumetric glassware using all certain digits plus one uncertain digit. Position the eye horizontally at the bottom of the meniscus to read the level of the liquid. D The volume of liquid is read at the bottom of its meniscus.The air resistance to the motion of a vehicle is something important that engineers investigate. As you may also know, the drag force acting on a car is determined experimentally by placing the car in a wind tunnel. For a given car, the experimental data is generally represented by a single coefficient that is called the drag coefficient. It is given by the relationship: Cd = Fd/(1/2)pV2A.
