1. Air enters a circular duct with a Mach number of 3.0. The friction factor is 0.01.
(a) How long a duct (measured in diameters) is required to reduce the Mach numb to 2.0?
2. A 50 x 50 cm duct is 10 m in length. Nitrogen enters at M1 = 3.0 and leaves at M2 = 1.7, with T2 = 280 K and P2 = 7 x 104 N/m2.
(a) Find the static and stagnation conditions at the entrance.
(b) What is the friction factor of the duct?
a closed steel bottle contains carbon dioxide at -20 degrees c x20 and the volume is 0.05 m3. it has a safety valve
A wall consists of two layers of insulation pressed against each other. Do we need to be concerned about the thermal contact resistance at the interface in a heat transfer analysis or can we just ignore it?
a dynamics student is called on to investigate a two-car collision. its known that car a struck car b. mass of car a is
Why do you think it is important, when using a stroboscope, to start at a very high frequency and slowly reduce the frequency to the point of synchronisation?
