The float in rotameter is lifted by the liquid. Rotameter is calibrated for particular liquid or gas with its exact density. if we mount it horizontally float will not come to its original place.
Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.

An example of non-concurrent forces would be a book resting on a table where the weight of the book is acting vertically downward and the normal force from the table is acting vertically upward in the opposite direction. Another example is a car driving on a curved road where the centripetal force required for circular motion is acting horizontally inward, while the frictional force between the tires and the road is acting horizontally outward.
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
Air pressure exerts a vertically upward force on a ceiling due to the weight of the air above pushing down on the air below. This pressure difference results in a net force that pushes upward on the ceiling, according to Newton's third law of motion.
The vertical component of the initial velocity of the ball thrown horizontally from a window is zero. The ball's initial velocity in the vertical direction is influenced only by the force of gravity, not the horizontal throw.
The direction of acceleration would be vertically upward, since the net force is acting in that direction. The horizontal motion of the balloon being blown westward does not affect the acceleration in the vertical direction.
The blown film process is operated in a vertically upward direction to allow the molten plastic to cool and solidify as it travels up the tower. This method helps to control the thickness and properties of the film as it is stretched and cooled, resulting in a more uniform film with desired characteristics. Additionally, operating the process vertically makes it easier to manage and maintain the equipment.
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.
A dome formed by thick magma that pushes upward rather than horizontally.
No problems, they aren't always straight.
A candle flame points upward when placed horizontally due to the convection currents created by the heat of the flame. The heat causes the surrounding air to warm up and rise, creating a flow of air that pulls the flame upward. Additionally, the flame itself is composed of hot gases that are less dense than the cooler air around them, further contributing to the upward movement. This phenomenon demonstrates the principles of buoyancy and convection in fluid dynamics.
