Show a sketch of a pitot-static tube. (ii) describe the constraints (assumptions) of using (2000) (i) the bernoulli equation for the pitot-tube velocity measurement. (ii) a pitot-static tube is used to measure the speed of air at standard conditions a point in a flow. it is assumed that the maximum speed be no more than 90 m/s. determine the manometer deflection, in millimeters of water, that corresponds to the maximum desirable speed. air density is 1.225 kg/m at t-15°c

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
