"Liquid quantity per hour" is a flow rate. It can be (any unit of volume) divided by (any unit of time).
Some widely-used candidates are:
-- cubic feet per minute
-- gallons per minute
-- liters per second
etc.
Momentum
A kilowatt (1000 watts) is the unit of measurement for the current consumed per hour.
It is not.913 miles per hour is a measure of speed while kilometres are a measure of distance. To get speed you need a unit of time. The SI unit is a second, so using that as the unit of time,913 miles per hour is 0.408 kilometres per second.It is not.913 miles per hour is a measure of speed while kilometres are a measure of distance.

Density.
There is no such unit as a 'watt per minute' or a 'kilowatt per hour'.
This is the definition of rate. It describes how one quantity relates to another as a ratio: meters per second, miles per hour, dollars per gallon. for example
The quantity of matter per unit volume is the density.
(55 miles per hour) is a scalar. (55 miles per hour heading north) is a vector.
No, it's a scalar quantity. ;)
Momentum
The contribution per machine hour is the contribution per unit divided by the number of machine hours per unit.
Speed is scalar quantity where as velocity is vector quantity. Unit is same as distance by time i.e. meter per second, kilometer per hour. Hence, either speed or velocity does not exist without time.
Yes, although it does not specify 15 WHAT per hour. [Run] 15 miles per hour or [make] 15 dollars per hour or [manufacture] 15 widgets an hour. To that extent, it is not a unit rate.
"Pascal" is a unit of pressure, not a quantity of air. The phrase "pascal per minute" is meaningless.
A kilowatt (1000 watts) is the unit of measurement for the current consumed per hour.
15 dollars/hour is the unit rate
