As the Glomerular Hydrostatic Pressure (GHP) goes up, the Filtration rate goes up.
Constricted arterioles in the glomerulus can lead to a decrease in the glomerular filtration rate (GFR) by reducing the amount of blood flow entering the glomerulus. This can result in decreased filtration of waste and reduced urine production.
Increasing the beaker pressure will increase the glomerular pressure. This is because the pressure in the glomerulus is dependent on the pressure in the renal artery, which is influenced by the pressure in the beaker. As the beaker pressure increases, it will lead to higher pressure in the renal artery and subsequently in the glomerulus.
Sympathetic stimulation causes vasoconstriction of the afferent arterioles in the kidneys. This response reduces blood flow into the glomeruli, which can decrease glomerular filtration rate (GFR). The effect is part of the body's mechanism to prioritize blood flow to vital organs during stress or low blood volume situations. Ultimately, this helps conserve water and maintain blood pressure.
Low blood pressure means the blood flow through the circulation system has been delayed. As a result, blood flow goes through the Renal tubules will be effected. Blood goes through that tube won't be much. Hence, Blood will be slowed when it passes by the renal tubules.
Pressure can have a small effect on the solubility of gases in a solution, with solubility generally increasing with higher pressure. However, pressure typically does not have a significant effect on the solubility of solids or liquids in a solution.

increase afferent radius or decrease efferent radius depending on the degree of change in blood pressure
Generally speaking, it would increase. However, it depends on the reason for the hypertension. For instance, if there is an obstruction or constriction of the renal artery (stenosis, malignancy, etc...) the physiologic affect would to increase the body's BP. This is due to the fact that the obstruction is decreasing hydrostatic pressure to the glomerulus, and transiently decreasing GFR. The body compensates by increasing BP to increase GFR. Patients that present with a renal artery stenosis could in fact be hypertensive with a decreased GFR.
As the afferent arteriole dilates it exposes the glomerulus to an increased blood pressure, closer and closer to that of the full systemic blood pressure. This increases GFR and Glomerular pressure. -6th Year Medical Student

The hypothesis that fluid filtration through capillary membranes is dependent on the balance between the pressure the blood places on the membranes and the osmotic pressure of the membranes. The law relating to the passage of fluid out of a capillary depending on the hydrostatic and osmotic pressures of the blood and the same pressures of tissue fluid, the net effect of the opposing pressures determining the direction and rate of flow.

Gravity has a significant effect on fluid pressure by creating a hydrostatic pressure gradient, which causes fluids to flow from areas of higher pressure to lower pressure. In a fluid column, gravity increases pressure linearly with depth, as described by the hydrostatic pressure equation. Additionally, gravity affects the behavior of fluids in confined spaces, such as causing stratification of denser and less dense fluids based on their buoyancy.
reducing afferent arteriole radius decreases filtration rate

on a pressure meter it has no effect
Aging typically leads to a gradual decline in glomerular filtration rate (GFR) due to changes in kidney structure and function. This decline is a normal part of aging and is often associated with a decrease in the number of functioning nephrons and reduced renal blood flow. This reduction in GFR can contribute to age-related kidney diseases and changes in medication dosages in older adults.
