1. Please list three specific regulations found in Forest Practices Illustrated that you found surprising, and explain why these regulations (or lack of regulations!) were surprising to you. What might you have expected to be different 2. Please discuss three things found in Forest Practices Illustrated that you found confusing, A. B. C.  3. Please […]

In Problem 9, what would be the effect on the line flow rates and node pressures if a pump with the head flow-rate relationship were placed in line 10? Problem 9 Determine the flow rate in each line and the pressure at each node for the system shown in Fig. P1-9. The Hazen-Williams coefficient.is 100,

1. A light oil at 1OO°Fis to be pumped in a 1,OQO-ft-longnominal Sdn, schedule 40 pipe. Devise a procedure to evaluate and in the Hazen-Williams head loss expression for this pipe. Determine the flow rate in each line and the pressure at each node for the system shown in Fig. P1-9. The Hazen-Williams coefficient.is 100, and

A military jet transport uses lP-4, a kerosene like fuel. The fuel distribution network is shown in Fig. P1-12. What pressure and power must the booster pump at A develop if the minimum inlet pressure at the engines (H, C, F, E) is 2.5 bar? The head prior to the pump is 12N-m/kg.

In Problem 9 what would be the effect on the line flow rates and node pressures if a device with a pressure-drop relationship of were placed in line 6? Problem 9 Determine the flow rate in each line and the pressure at each node for the system shown in Fig. P1-9. The Hazen-Williams coefficient.is 100,

(a) Room-temperature water flows between two reservoirs through two cast-iron pipes that are connected in series, as shown in Fig. P1-13. The entrance, exit, and pipe interface are sharp edged. Including minor losses, calculate the flow rate. The free surface of the water in tank A is 20 m higher than that of tank B.

Water at 200°F flows through the pipeline system shown in Fig. P1-14. The pressure PA in tank A is 70 psig. The entrance to the pipe system is sharp edged. The lengths are What diameter of schedule 40 pipe would be required to deliver 1 fe /s of water? Fig. P1-14

(a) Solve the following network (see Fig. P1-19). The Hazen-Williams coefficient is 110. (b) Filters with a head loss of 25.0Q2 are placed in the lines shown. A pump is placed in line 9. Find the required increase in head of the pump in order that 2.0 cfs flows through the line containing the pump.

(a) For the network shown in Fig. P1-15(a), find the flow rate in each pipe and the pressure at each node if the pressure at node A is 100 psig (C = 100). (b) If heat exchangers and valves are added as shown in Fig. P1-15(b), find the “C” values needed for the valves if
