Determine the total mass flow rate at the inlet of a turbofan if the flow rate at the inlet of the core is 25-kg/s and the bypass ratio is 7.6:1. Also, solve for the thrust produced if the mass flow rate both at the exhaust of the engine and inlet of the fan is 20-kg/s. Assume: Vo = 270-m/s Vf = Vc = 290-m/s Ve = 350-m/s.

3. A certain substance has a mass of 1200 kg and a volume of 0.952 cu.m. Find the following (a) weight (b) mass density (c) specific weight and (d) specific gravity.

"Lake Mead, near the Hoover Dam, which is the largest man-made lake in the United States, contains 28,537, 000 acre-feet of water (an acre-foot is the amount of water required to cover 1 acre to a depth of 1 foot). Express the mass of the water volume in kg and lbm."

What form of energy from the list below is an extensive system property (choose all what apply) total energy of a system potential energy kinetic energy O internal energy

The joule is a unit of work(or energy), defined by 1 joule = 1 newton meter. Convert 8 joule to ft·lbf. 21.653 x ft lbf

The specific weight of an object is: Equal to the mass density of the object divided by the acceleration of gravity. The same as the mass density of an object. Calculated as the mass of an object divided by the volume of the object. O Equal to the product of the mass density of the object and the acceleration of gravity.

The specific heat of copper is 0.093 cal/(g.°C) and the specific heat of gold is 0.031 cal/(g.°C). If 5.8 cal is supplied to one gram of copper and one gram of gold, the RATIO of temperature increase of gold to that of copper is
