INTERNATIONAL TRANSPORTATION Transportation plays an important part in international business because goods produced have to be delivered to the buyers abroad, and the delivery of goods is to be made possible by transportayion services. Goods are carried by several means of transportation - on road or rail, by sea or air.And in recent years,combined transportation which is a road-sea-rail carriage has appeared. With the expansion of international trade, the container service has become popular. The use of containers provides a highly effective form. of transportation by road, rail and sea. Basically, about 98% of world trade is carried out by sea transportation.Besides transportation by sea, road, or rail, nowadays in order to speed up delivery, carriage by air has also become popular.1.

Due to the large amount of heat picked up by the air in boiler and engine rooms, it would be impracticable to maintain ambient conditions within the comfort zone by air conditioning or any other means. The normal practice is to provide copious mechanical ventilation; in boiler rooms, the quantity is equated to the combustion requirements, while in a motor ship engine room the supply may be 25-50% in excess of the requirements of the engines.The axial flow fan is particularly suited to handle these large air volumes at the moderate pressures required, while of course the “straight-through” flow feature places it at an advantage over the centrifugal fan.The increasing adoption of automation, with the provision of a separate control room makes less significant the fact that comfort conditions cannot be maintained in the engine room all the time. Which of the following devices should be taken to maintain ambient conditions of the boiler and machinery space?A.air compressorB.air coolerC.air-conditioning plantD.mechanical ventilation plant
