Mathematical Model and Experimental Characterization of Vertically
The pressure applied on the capacitor is changed by adjusting the load by applying different weights on the upper supporting structure. For each experiment, the rod is placed on top of the capacitor and loads are placed until a predetermined pressure (force divided by the rod surface area) is reached by stacking loads in sequence.
Will capacitance changed if horizontally mounted.
There should be no change other than natural aging as capacitors may be mounted in any orientation unless the manufacturers data sheet specifies differently, (which

At equilibrium, the angle between the wire and the vertical direction is α.
Should ventless electrolytic capacitors be mounted
Proper orientation is upright, or horizontal with the vent at the top of the capacitor. Smaller electrolytic capacitors often do not have such a vent, instead having a scored top.
Vertical
Vertically stacked MLC capacitors from KYOCERA AVX are characterized with very high capacitance in a small volume. By vertical stacking of the ceramic elements, the footprint required for mounting the capacitors is greatly reduced. Additionally, vertical stacking of the capacitors improves ESR and ESL characteristics in the device.

6 FAQs about [Capacitors are placed vertically]
Can a capacitor be mounted vertically or perpendicular to a microstrip?
This article talks about mounting capacitors with the electrodes parallel or perpendicular to this microstrip indicating that "By mounting the capacitor vertically, that is, with the electrodes perpendicular to the microstrip, the first parallel resonance will not be present thereby significantly extending the usable bandpass."
Can a capacitor be mounted upside down?
The capacitor should not be mounted upside down, (safety vent facing down) (Figure 3 - A). However, if the PCB is mounted in the vertical direction on the application, this position can be allowed (capacitor in a horizontal position see Figure 3 - B). Figure 3 - A Figure 3 - B Figure 3 - (A) Upside down position not recommended.
How are capacitors connected to each other?
They are then connected to each other in parallel with plates of like sign connected. Finally, the plate separation in one of the capacitors is doubled. (Use any variable or symbol stated above as necessary.) (b) This problem has been solved!
What happens if a capacitor is placed in parallel?
When capacitors are placed in parallel, the total capacitance will be the sum of all individual capacitances. This is because capacitors store charge, and when placed in parallel, each capacitor will have the opportunity to store a portion of the total charge.
Can capacitors be stacked together?
It's possible to stack the capacitors (Figure 2- B) to achieve a low height profile or to place them in an upright position bank (Figure 2 - A) to reduce the PCB footprint. Banks of capacitors mounted together will benefit from an adhesive applied to them, creating a rigid structure.
Can a capacitor be mounted without cooling?
The capacitor is designed for mounting with- or without- cooling by heat-sink. With the capacitor mounted to a metallic chassis (heat-sinked capacitor body), the ripple current capability is significantly improved. Mounting with heat-conductive adhesive or paste, will improve the cooling condition.
