National cultures and management styles

Case 3b: National cultures and management stylesMichael Savvas, Aberystwyth UniversityPetro decided to research cross-cultural management. He was interested particularlyin national cultures and wished to compare and contrast differences between Britain,France and Nigeria in terms of their management theory and practices. He spentseveral days in the university library searching the online catalogue for information onnational cultures

Wind tunnel

The wind tunnel in the Mississippi State University Thermal and Fluid Dynamics Laboratory has a cooling water loop which is used to control the tunnel operating temperature. The loop is shown in Fig. P4-13. The water temperature is controlled by continuously dumping hot water and mixing in cool water from the plant water system. The

Commercial steel pipeline

Water at 180°F is to be pumped through a long schedule 40, 3-in. commercial steel pipeline. At steady-state operation, a Goulds 2 X 3-13 pump (Fig. 4-18) is operating at 180 gpm and 152 ft-lbf/lbm head. The pressure at the inlet to the pipeline is 14.7 psia. Find the pump placement required to prevent cavitation

The operating point

Three pumps are placed in the following arrangement as indicated in Fig. P4-11: If the system characteristic is H = 120.0+0.016586Q1.73,where H is in ft-lbf/lbm and Q is in gpm, find the operating point for each pump. Find the power required for each pump if the fluid density is 53.7Ibm/ft3 *

The oil-cooler system

The oil-cooler system of a ship’s turbine consists of a reservoir in which light oil is maintained at 300°F, a 200-ft segment of 3-in. schedule 40 commercial steel pipe in which oil at 300°F is transported, a heat exchanger with a head loss of 257.l3Q1.73(Q in ft3/sec and head loss in ft-lbf/lbm), a 200-ft segment

Pump operating point

Hot water, initially at 200°F and 14.7 psia, is piped through a series system that is 1,000 ft long and contains 12 elbows, a heat exchanger, and a plug disk glove valve. Schedule 40 pipe of 3-in. nominal diameter is used. The head loss across the heat exchanger is = 2388.7~, where Q [==] ft3

Same system characteristic

Several Goulds 2 X 3-10 (A60) pumps (Fig. 4-16) are used in series and parallel pumping arrangements. In one series arrangement (system characteristic H = 0.146Q2) and one parallel arrangement (system characteristic H = 0.00032Q2) there are two pumps with 10-in. rotors, both at 1,750 rpm. In another series arrangement and another parallel arrangement (same

The pump’s location

For the system shown in Fig.P4-14, a Goulds 2 X 3-13 (Fig.4-18) with a 12-in.rotor is used to pump 250 gpm from the lower to the upper reservoir. The liquid being pumped is water at 175°F. (a) Neglecting friction, what restrictions are there on the pump’s location? (b) If friction were considered, would it increase
