Oil enters the bend of a pipe in the horizontal plane with velocity 4 ms−1 and pressure 280×103 Nm−2 as shown in the figure. The pressure of oil at the point Q is n×102 kNm−2. Then n= (Take specific gravity of oil as 0.9 and sin37∘=0.6)

Oil enters the bend of a pipe in the horizontal plane with velocity 4

1.	Oil enters the bend of a pipe in the horizontal plane with velocity 4 ms−1 and pressure 280×103 Nm−2 as shown in the figure. The pressure of oil at the point Q is n×102 kNm−2. Then n= (Take specific gravity of oil as 0.9 and sin37∘=0.6)
Answer» Oil enters the bend of a pipe in the horizontal plane with velocity $4 {ms}^{- 1}$ and pressure $280 \times 10^{3} {Nm}^{- 2}$ as shown in the figure. The pressure of oil at the point Q is $n \times 10^{2} {kNm}^{- 2}$ . Then $n =$ (Take specific gravity of oil as 0.9 and $sin 37^{\circ} = 0.6$ )
