12. The acceleration of gravity is given as a function of elevation above sea level by the relationg-9.81 - 3.32 X 10-6 h (m/s³) with 'h' measured in meters. What is the weight of an airplane at10,000ft elevation when its weight at sea level is 40 kN?a. 39.9583KNb. 39.9584kNc. 39.9587kNd. 39.9522kN13. How many kilojoules in one (1) BTU?a. 778b. 2.11c. 0.2520d. 1.05514. A 2.5-m' rigid tank initially contains air whose density is 1.18 kg/m³. The tank is connected toa high-pressure supply line through a valve. The valve is opened, and air is allowed to enter thetank until the density in the tank rises to 5.30 kg/m³. Determine the mass of air that has entered thetank in Ib.a. 25.4678lbb. 25.3399|bc. 26.4865lbd. 22.7115lb15. Three (3) adjacent bodies whose initial temperatures are 150°F, 350ºF and 60°F have specificheats of 2lb-ft/lb-°R, 4lb-ft/b-°R and 3.21lb-ft/lb-°R respectively. They are all placed inside a closedadiabatic (perfectly insulated) container until the equilibrium condition. If the first two (2) objectshave a masses of 5lb, 3lb respectively, determine the mass of the 3rd body if the equilibriumtemperature is attained at 87.5°Fа. 39.22081bb. 41.4787lbc. 42.8977lbd. 39.7227lb

Velocity squared divided by double gravity is called the velocity head. If the mass entering a tank is greater than the mass exiting the tank, then the amount of mass in the tank will decrease through time. A flow in a pipe that has a Reynolds number of 105 would be considered a T F T F T F turbulent. d. T F The partial derivative of velocity with respect to time is called the convective acceleration. F The center of pressure is never above the centroid of a planar surface. An object submerged in oil (S = 0.88) will have a smaller buoyant force acting on it than when it is submerged in water. Turbulent flow in pipes tends to have a more uniform mean velocity profile than laminar flow in pipes. The Bernoulli equation requires that the two points in question are on the same streamline. e T F F h F i The weight of an object is different under water than it is out of the water.
