Calculating Nozzle Flow Rate - Physics Forums Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
Is velocity ever a scalar quantity? • Physics Forums I thought velocity was always a vector quantity, one with both magnitude and direction When it came to the suvat equations, where v = final velocity, and u = initial velocity, I thought both of those were vector quantities, e g; v (final velocity) 112km hr North u (initial velocity) 0km hr
How to Determine Velocity from a Force-Time Graph? Hey all, I've been attempting this all week and can't get my head around what the proper way to calculate the answers for this query is so 1 Homework Statement The force shown in the force-time diagram acts on a 3 4 kg object (a) Find the impulse of the force (b) Find the final
Average Speed vs. Velocity: Explained • Physics Forums Though average speed over a finite interval of time is greater or equal to the magnitude of the average velocity, Instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant Why so?
Relation Between Spring Constant and Angular Velocity I was going through Periodic Motion chapter of my book and came across an equation while defining the relation between Time Period of on oscillating particle and force constant k m=w2 which was applied in, T = 2xpie angular velocity can anyone please help me define this equation I can't seem
