What else can I help you with?
If vessel length increases then resistance will?
Yes, theoretically there is more surface area inside the vessel to create friction and slow the fluid down, also there will be more fluid in the vessel at any given moment so its inertia will be greater thus increasing it's "resistance".
What is Propulsion resistance?
Propulsion resistance refers to the resistance encountered by a vessel or vehicle as it moves through a fluid, such as water or air. This resistance is primarily due to the friction between the fluid and the surface of the vessel, as well as the pressure differences created by its motion. In maritime contexts, propulsion resistance is a key factor in determining the efficiency of a ship's propulsion system, affecting fuel consumption and speed. It can be influenced by factors such as hull design, speed, and the viscosity of the fluid.
What blood vessel regulates systemic resistance?
which blood vessel regulates systemic resistance?
How did the hovercraft reduce friction?
Hovercraft reduce friction by using a cushion of air to lift the vessel above the surface, allowing it to move with minimal resistance. The air cushion acts as a buffer between the vehicle and the surface, reducing the effects of friction. This allows hovercraft to glide smoothly over various terrains, including water, ice, and land.
Which blood vessel offer most resistance to blood flow?
Arterioles generally have the highest resistance because they are so extremely small.
What is the principles relating to blood flow and pressure and resistance?
Blood pressure = (Blood flow)(Resistance). This equation is usually found in the following form: MAP = (CO)(R) Where MAP is the mean arterial pressure CO is the cardiac output R is the peripheral resistance
Factors that affect vascular resistance?
Vascular resistance is influenced by factors such as vessel radius, vessel length, blood viscosity, and vessel compliance. Changes in these factors can impact the resistance to blood flow in the vasculature, affecting blood pressure and overall circulatory function.
Which of the following is NOT an important source of resistance to blood flow?
An important source of resistance to blood flow is not low blood viscosity, as low viscosity would actually decrease resistance. The important sources of resistance to blood flow are vessel diameter, vessel length, and blood viscosity.
What is the effect on resistance if the radius of a vessel is halved?
If the radius of a vessel is halved, the resistance will increase by a factor of 16. This is because resistance is inversely proportional to the fourth power of the radius (R ∝ 1/r^4). Therefore, a decrease in radius leads to a significant increase in resistance.
What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
What are the main factors that contribute to total peripheral resistance?
Total peripheral resistance is mainly influenced by the diameter of the blood vessels, vessel length, blood viscosity, and the compliance of the vessel walls. Vasoconstriction and vasodilation also play a significant role in regulating total peripheral resistance. Additionally, factors such as arterial blood pressure and neural and hormonal control can impact total peripheral resistance.
What is the effect of increased vessel length on blood flow?
The longer the vessel is the more friction it applies on the passing blood, the less the blood flow is.
