Determine the mass ratio (Burnout mass/ Initial mass) of a vehicle in a gravitation less space if its velocity is boosted from 800 m/s to 1600 m/s and the effective rocket exhaust velocity is 2000 m/s.
For a rocket traveling at 700 m/s having an exhaust velocity of 1.4 km/s, exhaust gas density of 0.3 kg/m3, nozzle throat diameter of 0.14 cm and nozzle exit diameter of 25 cm, find the total mass flow rate of the propellants.
The velocity of the engine exhaust flow is a function of the temperature of the exhaust gas.
In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Air conditioning is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments.  B: Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. C: Air conditioners often use a fan to distribute the conditioned air to an enclosed space such as a building or a car to improve thermal comfort and indoor air quality.  D: This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals.
