It depends on the submarine type and hull design.
Older WWI and WWII Fleet submarines were specifically designed as surface ships with limited submergence capability - they primarily ran on the surface with their diesel engines, and submerged using their battery powered electric motors when attacking a surface vessel. This hull design made gave them a lower water resistance on the surface, but much higher underwater. Their speed underwater was almost half of what they could do on the surface.
With modern submarines, the opposite is true. Submarines today are specifically designed for lower water resistance (higher speeds) underwater than they are on the surface. Top speed for most boats on the surface might approach 20 knots, but underwater they can do over 30 knots. The old Russian ALFA class submarines were known to do 45 knots submerged.

Does fluid friction move a submarine through water?
Fluid friction is defined as occurring between layers within a fluid that are moving relative to each other. It is a resistance so it does not move a submarine through water.
Is the marginal benefit of a glass of water large or small?
water is necessary for life, is the marginal benefit of water is large or small?
Why does a submarine can sink and float in water?
because the submarine has the water tank.when the tank is filled then submarine sink in the water.and when the tank is empty then submarine float in water.
Is excess water reabsorbed from the small or large intestine?
The small intestine absorbs food and the large intestine absorbs water.
How does water pressure affect a submarine?
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
Is water absorbs in the small or large intestine?
large
How can resistance be decreased?
Aerate the water: pump lots of small air bubbles into it.
Is a 15ml reservoir a small or a large amount of water?
large
Can water exert pressure on a submarine?
Yes, water exerts pressure on the hull of the submarine.
Large water add to small acid?
Never add water to an acid always add small amount of acid slowly in large amount of water.
How does water enter the submarine?
Water enters the submarine by letting water out not into its ballast tanks it enters from the flagura to the magura.
A sentence with submarine in it?
A submarine is only used under water.
