Kunci Jawaban Soal Essai Paket A.pdf

Kunci jawaban Babak FINAL Jenis soal : ESSAY 1. Kinerja bensin diukur berdasarkan nilai oktan (octane number) yaitu keberadaan senyawa 2,2,4 - trimetil pentane (isooktana) dengan nilai oktan 100, sedangkan nheptana nilai oktannya adalah nol. a. Gambarkan struktur 2,2,4 – trimetil pentane dan n – heptana (20 Point) Penyelesaian : b. Gambarkan semua isomer struktur n-heptana dan namai secara IUPAC (30 Point) Penyelesaian : c. Gambarkan struktur dan nama IUPAC alkena paling sederhana yang mempunyai isomer cis dan trans. (30 Point) Penyelesaian : d. Jelaskan pengertian bensin dengan angka oktan 75 % (20 Point) Penyelesaian : Angka oktan pada bensin ditentukan dengan adanya senyawa trimetil pentane dan nheptana dimana apabila pada bensin memiliki angka oktan 100 % maka pada besin tersebut terkandung senyawa trimetil pentane banding senyawa n-heptana yaitu 100 : 0, sehingga apabila bensin dengan angka oktan 75 % maka dalam bensin tersebut terkandung 75 % senyawa trimetil pentane dan 25 % senyawa n-heptana. 2.

INSTALLATION TIPS $15.00 INSTALLATION GUIDELINES ® PRODUCT INFORMATION The first name in vehicle ® safety systems® APPLICATION GUIDELINES CUSTOM HARNESS GUIDELINES ULTRA BLUE SEAL® WIRING HARNESS HANDBOOK DESIGN GUIDE PLANNING WORKSHEETS COMPONENT LISTS SYSTEM OVERVIEW FEATURES & BENEFITS PERFORMANCE SPECS VAN-TYPE TRAILERS 28-FOOT TRAILERS 48-FOOT TRAILERS 53-FOOT TRAILERS FLAT BED TRAILERS TANK TRAILERS CONTAINER-CHASSIS TRAILERS DOLLY CONFIGURATION REAR SILL HARNESSES MAIN HARNESS ABS DROPS CONNECTOR SPECIFICATIONS Ultra-Blue Seal® System The Modular Plug & Go Connection System from Grote Modular Design The UBS system provides true “Plug & Go” modular convenience and reliability for trailer electrical installations. It’s designed around a family of standardized components that plug together to form complete lighting and wiring systems. UBS components can be used to create systems for most styles and sizes of trailers including dry vans, tankers, reefers, flat beds and special task trailers such as container chassis. The modular design means that all UBS components provide positive connectivity no matter what the design function and position on the trailer requires. Grote engineers design our lamps to fit our plugs and our plugs to work with our lamps. Interchangeability The modular design also means that the components can be changed without requiring cutting and splicing into the harness system. If for instance a jumper is damaged, it can be changed with a new, replacement part without the need for trimming to length, crimping or soldering. Double Seal Technology At the heart of the UBS system is the patented Grote Double Seal feature. It provides double protection from moisture and contaminants. The Double Seal effect results from a molded-in circular ring in the connector, which corresponds to a mating ring on the lamp. The inner sealing ring covers the terminal area and outer ring, or dust skirt, seals around the outside area of the lamp plug connection. The Double Seal drastically decreases water intrusion and corrosion. Another UBS advantage is the Grease Groove design on the male-pin plugs. Dielectric grease added to female terminals and male terminals to ...

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads. History Warman centrifugal pump in a Coal Handling and Preparation Plant (CHPP) application According to Reti, the Brazilian soldier and historian of science, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini.[1] True centrifugal pumps were not developed until the late 17th century, when Denis Papin made one with straight vanes. The curved vane was introduced by British inventor John Appold in 1851. How it works Like most pumps, a centrifugal pumps converts mechanical energy from a motor to energy of a moving fluid; some of the energy goes into kinetic energy of fluid motion, and some into potential energy, represented by a fluid pressure or by lifting the fluid against gravity to a higher level. The transfer of energy from the mechanical rotation of the impeller to the motion and pressure of the fluid is usually described in terms of centrifugal force, especially in older sources written before the modern concept of centrifugal force as a fictitious force in a rotating reference frame was well articulated. The concept of centrifugal force is not actually required to describe the action of the centrifugal pump. In the modern centrifugal pump, most of the energy conversion is due Cutaway view of centrifugal pump to the outward force that curved impeller blades impart on the fluid. Invariably, some of the energy also pushes the fluid into a circular motion, and this circular motion can also convey some energy and increase the pressure at the outlet. The relationship between these mechanisms was described, with the typical mixed conception of centrifugal force as known as that time, in an 1859 article on centrifugal pumps, thus:[2] Centrifugal pump To arrive by a simpler method than that just given at a general idea of the mode of action of the exterior whirlpool in improving the efficiency of the centrifugal pump, it is only necessary to consider that the mass of water revolving in the whirlpool chamber, round the circumference of the wheel, must necessarily exert a centrifugal force, and that this centrifugal force may readily be supposed to add itself to the outward force generated within the wheel; or, in other words, to go to increase the pumping power of the wheel. The outward force generated within the wheel is to be understood as being produced entirely by the medium of centrifugal force if the vanes of the wheel be straight and radial; but if they be curved, as is more commonly A centrifugal pump uses a spinning "impeller," the case, the outward force is partly produced through the which normally has backward-swept blades that medium of centrifugal force, and partly applied by the vanes to directly push water outward. the water as a radial component of the oblique pressure, which, in consequence of their obliquity to the radius, they apply to the water as it moves outwards along them. On this subject it is well to observe that while the quantity of water...
