Reed water tube boiler straight tubes through which water and steam circulated more freely, it was considered by some contemporary writers on the subject such as Leslie S. Robertson as "behind" in its circulation because of the absence of down-comers. Whereas the Yarrow boilers fitted to the armoured cruiser of 1905 evaporated 11.664 pounds (5.291 kg) of water per pound (454 g) of coal at 100 degrees centigrade (212 degrees Fahrenheit) with natural draught, by the same measure a Reed boiler as fitted to the torpedo boat destroyer of 1896 evaporated 12 pounds (5.44 kg). An advantage of the Yarrow boiler was in weight:
Red Sea–Dead Sea Water Conveyance number of international donors. The water level in the Dead Sea is shrinking at a rate of more than one metre per year, and its surface area has shrunk by about 30% in the last 20 years. This is largely due to the diversion of over 90% of the water of the Jordan River. In the early 1960s, the river moved 1,500 million cubic metres of water every year from the Sea of Galilee to the Dead Sea. Dams, canals, and pumping stations built by Israel, Jordan and Syria now divert water for crops and drinking, and have reduced the
