Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N.

5. A sprue is 200 mm long. The velocity of the molten metal at the top of the sprue is 0.1 mm/sec. The sprue has a diameter of 10 mm at the bottom. The total cavity of the "runner system + mold" is 1.2 liters. The viscosity of the molten metal is 0.002 Pa. s and density 2000 kg/m 3. a) What is the velocity of the molten metal at the bottom of the sprue in [mm/s]? b) What is the flow rate in [mm3/s]? c) How much time does it take to fill the mold? d) For a proper design, what should be the diameter of the sprue at the middle (corresponding to z= 200/2 mm) of the sprue? e) Is the flow laminar, mixed, or turbulent at the bottom of the sprue? h++ Pg Zg constant 2 = Av = Av.

help please, round answer to 3 sig figs
seems 1st one is the right answer, could you please clarify.
Question 3 pls. Complete solution. Thanks
Please include solution. Thank you!
A) All these statements are false give the right answer: 1- Copula furnace is used for welding process. 2- In hot chamber die casting the metal is melted separately in a furnace. 20 3- The core is defined as the hole through which molten metal enters the sand mold. 4- Continues casting is suitable for production tubes. 5- Shell casting is one of the types of hot chamber die casting. 6- Investment casting is one of the types of cold chamber die casting. 7- Impact extrusion is most suitable for producing collapsible tubes made of Cast Iron. قالب بلغة الباردة الصب لمسم
