¿Cuáles aseveraciones son correctas? * El calor que hace en verano se mide en grados Celsius y la temperatura de nuestro cuerpo se mide en calorías. El calor es sumar toda la energía cinética de las moléculas de un cuerpo y la temperatura es el promedio de la energía cinética. Generalmente en los países ingleses la temperatura se mide en grados Fahrenheit y en México en escala Celsius la escala termométrica del Sistema Internacional de Unidades es la Kelvin y se conoce como Cero Absoluto Para transferir calor por conducción es a través de corrientes de fluidos y por radiación es por contacto.

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?
