Figure 7.36 shows a diagram of a fluid power system for a hydraulic press used to extrude rubber parts. The following data are known:

1. The fluid is oil (sg = 0.93).

---

2. Volume flow rate is 175 gal/min.

---

3. Power input to the pump is 28.4 hp.

---

4. Pump efficiency is 80 percent.

---

5. Energy loss from point 1 to 2 is 2.80 lb-ft/lb.

---

6. Energy loss from point 3 to 4 is 28.50 lb-ft/lb.

---

7. Energy loss from point 5 to 6 is 3.50 lb-ft/lb.

Compute the power removed from the fluid by the press.
