Oil is flowing at the rate of 0.015 m3/s in the system shown in Fig. Data for the system are as follows:

• Oil specific weight= 8.80 kN/m3

---

• Oil kinematic viscosity= 2.12 × 10-5 m2/s

---

• Length of 6-in pipe = 180 m

---

• Length of 2-in pipe = 8 m

---

• Elbows are long-radius type

---

• Pressure at B = 12.5 MPa

Considering all pipe friction and minor losses, calculate the pressure at A.
