At two points area and velocity is same but pressure is different due to frictional losses, I am unable to understand what does this pressure drop means. what kind of physical difference will be there at second point and first point?
When pipe length increases (assume points A & B are at the same height), friction is added from the inside walls. This friction is retarding layers of fluid, as well as layers of the fluid itself retarding additional layers. Thus, pressure is lost from A to B in a straight length pipe, reducing efficiency. Recall that Energy-in = Energy-out. If you dig around, you likely find a video that can help you gain a better understanding of the principles.
@@Ap-zq7lb I think the velocity does not change, is constant, the static pressure decreases due to the friction loss, the dynamic pressure (and velocity) is constant, so the overall pressure decreases. From energy point of view, there is a friction loss, to keep fluid flowing, to keep kinetic energy constant (so the velocity constant), the energy is transfered from pressure energy into kinetic energy, the energy balance is there - > the pressure p2 decreases while kinetic energy is kept, see also previous video (12 of 38)
Science padh Li hoti ache se , petrol pump pe kam kar lo sab samajh a jayega Bharwa ke dekh lo 20 litre kisi tank me , wo bhi jump se, aur naap Lena Yaha meter sahi batata hai sir bas problem ye hai ki display me refresh rate slow ki wajah se Aur oil tab Tak jyada nikal jata hai Itne gyani ho bana ke dekh lo ek petrol pump mechine , Aisa hi theek speedometer me bhi hota hai Bike 1,2,5 na dikhaye aur 15 ki speed pakad le to bike chali hi nahi, are sarkar ko bolo aap aur government mil ke petrol rate kaise Kam karna hai aap log bahut gyani bhi Kya ek gareeb labour ke pichhe pade ho

@@JP-iq8td so velocity changes over length due to frictional losses.

Yaha meter sahi batata hai sir bas problem ye hai ki display me refresh rate slow ki wajah se
Aur oil tab Tak jyada nikal jata hai
Itne gyani ho bana ke dekh lo ek petrol pump mechine , Aisa hi theek speedometer me bhi hota hai
Bike 1,2,5 na dikhaye aur 15 ki speed pakad le to bike chali hi nahi, are sarkar ko bolo aap aur government mil ke petrol rate kaise Kam karna hai aap log bahut gyani bhi
