Depends what you're shipping through the pipe.
If it's air or natural gas, very few psi.
If it's crude oil or cookie dough, many many psi.
To convert pounds per square feet to pounds per square inch, you need to divide by 144 since there are 144 square inches in a square foot. In this case, 32 pounds per square foot would be equal to 0.222 pounds per square inch.
The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.
The answer is FALSE- acceleration would be correct
Pounds per square foot. If I understand your question correctly.
"Per second per second" sounds like a speech problem, but in Physics, velocity (or speed) is distance per second. If the velocity (speed) increases, then the acceleration is in units of distance per second (or velocity) per second.An example might make this more clear--If we jumped off a roof, gravity would make us accelerate. Your velocity at the end of the first second is 10 meters per second. Your velocity at the end of the next second is 20 meters per second, the end of the third would be 30, etc.So each second we fall the velocity increases (accelerates) by ....drum roll....10 meters per second per second. Which is the acceleration due to gravity ON THE EARTH. (actually 9.8 m/s/s or 9.8 m/s2, but close enough).
Square seconds, by itself, doesn't make much sense. On the other hand, please note that acceleration is not the same as speed or velocity, therefore you would expect the units to be different between the two. Speed or velocity is measured in meters / second; since acceleration is the change of rate of a velocity (in symbols: dv/dt), its units are velocity / time. Using SI units, that would be (meters / second) / second, and this is commonly written as meters / second2, which makes sense since the seconds appear twice in the denominator.
If you mean what is the SI unit for velocity, that would be the meter per second, or m/s
The velocity of a toothpick would depend on how fast it is moving. If it is stationary, its velocity would be 0 m/s. If it is moving, its velocity would be the rate of change of its position over time, measured in meters per second.

16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.

You need to know the cross sectional area of the pipe, this would be in square feet or square meters. Then take the volume flow in cubic feet per second, or cubic meters per second, and divide it by the area, this will give the velocity in ft/sec or m/sec V=(21.22*Q)/D2 V = velocity D= diameter of pipe Q= flow
the SI unit would be meter/second (m/s)
The skydiver's forward velocity after 1 second would depend on factors such as their body position, weight, and air resistance. On average, a skydiver in freefall might reach a forward velocity of around 120 mph (193 km/h) after 1 second.
Please reword this question, since in its present form, it doesn't make sense. Right now, it sounds like a square is flying through the air. Maybe you are asking about velocity squared? If so, velocity means both the speed and direction of something. For velocity squared, it would essentially be just multiplying the speed by itself.
I presume you mean 1 second after jumping from the plane. Since skydiver's fall, their velocity is generally in a downward direction, so the upward velocity is negative. The formula v = gt, where g is the acceleration due to gravity which is about 32.2 feet per second per second, tells us that after 1 second it would be about -32.2 feet per second.
