Answer:
<em>The direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>
Explanation:
The question is incomplete. So the picture, which is missing in question, is attached for your review.
As it can be seen in the picture, the ball coming out of the tube will have two components of velocity. One is along the length of tube (because ball is moving in that direction and is coming out from the hole), other is velocity component will be perpendicular to the tube (because the ball is made to move in that direction as the tube is rolling on the surface).
<em>So, taking the resultant of two vectors of velocity, the resultant direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>
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:
