Answer:
a)
, b)
, c) 
Explanation:
a) The tank can be modelled by the Principle of Mass Conservation:

The mass flow rate exiting the tank is:



b) An expression for the specific enthalpy at outlet is derived from the First Law of Thermodynamics:


Properties of water are obtained from tables:



The specific enthalpy at outlet is:


c) After a quick interpolation from data availables on water tables, the final temperature is:

Answer:
The correct answer is 'velocity'of liquid flowing out of an orifice is proportional to the square root of the 'height' of liquid above the center of the orifice.
Explanation:
Torricelli's theorem states that

where
is the velocity with which the fluid leaves orifice
is the head under which the flow occurs.
Thus we can compare the given options to arrive at the correct answer
Velocity is proportional to square root of head under which the flow occurs.
The Lamborghini SCV12 has 830 horse power.
Answer:
When you pull the trigger to shoot a shotshell from a shotgun or a cartridge from a rifle or handgun, the firing pin strikes the primer in the base of the cartridge or shotshell. This causes the primer to explode. The spark from the primer ignites the gunpowder, which burns rapidly and converts to a gas.
