The Arrowhead West Tunnel is 3.8 mi (6.1 km) long and 12 ft (3.7 m) in diameter. The tunnel begins at Devil's Canyon and is the first of the three tunnels in the feeder project. It continues east to the Waterman portal at Old Waterman Canyon Road and California State Route 18. The tunnel was constructed with a grade to allow water to flow by ...
VB-10,000 is a heavy-lift twin-gantry catamaran consisting of two truss space frames atop two barges.The design was derived from Versabar's earlier VB-4000 (aka Bottom Feeder), [1] [2] which was developed to clear debris from toppled oil drilling platforms in the Gulf of Mexico.
For both of these rules of thumb (85%/90% and major minus pitch), the tap drill size yielded is not necessarily the only possible one, but it is a good one for general use. The 85% and 90% rules works best in the range of 1 ⁄ 4 –1 in (6.4–25.4 mm), the sizes most important on many shop floors. Some sizes outside that range have different ...
Width over outer surface of the shell plating: 106 ft (32.31 m). General exception: 107 ft (32.61 m), when draft is less than 37 ft (11.3 m) in tropical fresh water. New Panamax originally allowed a width of 49 m (161 ft). [2] This was expanded to 51.25 m (168.14 ft) during June 2018. [3]
A different alternative to the concept of frontage roads in urban freeways is the local–express system, which is designed to handle closely spaced interchange ramps without disrupting through traffic. Unlike frontage roads, the local lanes are typically high-speed fully controlled-access lanes, conforming to freeway requirements.
The Dennis chassis for the Enviro500 (also known as the Trident E500 [1]) was modified from the Trident 3.It can be fitted with Cummins ISMe335 Euro III engine (later Cummins ISLe340 Euro IV/Euro V engine which uses AdBlue to reduce emission of nitrogen oxides through selective catalytic reduction process), or ISM-330 engine for the buses delivered to North America, and coupled to Voith ...
The boat has a draft of 6.00 ft (1.83 m) with the centerboard down and 2.25 ft (0.69 m) with the centerboard up, while the fixed fin keel version has a draft of 4.50 ft (1.37 m). [ 1 ] [ 4 ] The boat is usually fitted with a small 4 to 15 hp (3 to 11 kW) outboard motor , and less often were various gas and diesel inboard engines available from ...
The 2 × 25 kV autotransformer system is a split-phase electric power system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV system. In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail.
