Project problem: A pressure vessel is widely used in industry, i.e. power plants, oil and gas establishments and the like. The pressure vessel is a container that holds gases, vapor or liquids above the ambient pressure. The figure below shows a pressure vessel attached to L-shaped support via links AC-BC and bolts (assume the bolts act as pins). The L-shaped support and links are made of steel (you can assume carbon content 2%). The material of the pressure vessel is stainless steel 304. The internal pressure is 8 MPa excreted by the air at 30°C. The internal diameter of the vessel is given as I m, and the length of the pressure vessel is 2.5 m. 5. Design the minimum diameter (D) of the L-shaped support.

Problem 2 (20 points)-A vertical column of 1018 hot-rolled steel ( kpsi, kpsi, kpsi, kpsi) is 10 in wide. An attachment of the same material has been designed to support a static load of 20kip at a clearance in as shown in the figure. The attachment is welded with a E6010 electrode ( kpsi, kpsi, kpsi). The length of the weld bead is given by in and in. (a) Determine the primary shear on the weld as a function of theleg size . (b) Determine the secondary shear on the weld at a critical pointas a function of the leg size . (c) Determine the total shear at the critical pointthe leg size .as a function of (d) Using kpsi, determine the leg size .

Determine the turbine inlet area. The turbine inlet area is________m².

Super heated vapor enters the turbine at 10 MPa, 480°C, and the condenser pressure is 7.5 kPa of a steam Rankine power cycle. Isentropic efficiencies of the turbine and pump are 84% and 73%,respectively. Determine for the cycle a.Sketch the cycle of a T-s diagram. Indicate the isobars with their values and the values for temperature and entropy. The heat transfer to the working fluid passing through the steam generator, in kJ per kg of steam flowing.b. The thermal efficiency.с. d. Compute the entropy generated by the turbine per unit of mas of steam flowing. The heat transfer from the working fluid passing through the condenser to the cooling water, inkJ per kg of steam flowing. [Hint: this refers to the cooling tower]е.

Dr. Mays has a 300 mL aluminum water bottle with a threaded lid. On a summer day here in Denver when TI = 80°F, he drives to the supermarket with his car windows down. He then parks his car, rolls the windows up, drinks all but 150 mL of water, replaces the lid, and leaves the bottle inside the car. After shopping, the temperature inside the car is T2 140°F. What is the vapor pressure inside the bottle after shopping? [psi] The pressure deformed the flat base but not the cylindrical sides. Why? (<20 words)

The system bellow has mass of A kg and spring constants C is in N/cm. The system is excited by a force p(t) = D sin(4t) as shown in figure (D in Newton) A. If the system damping ratio 3=0.5, find the value of the damping coefficient "b". (10pts) B. By frequency analysis method find the steady-state response of the system. C. Find the maximum force transmitted to the left wall and percentage of force transmissibility to this wall. (10 pts)

A crate is supported on a lift table, as shown in the figure. The weight of the crate is W Ib. where: W = your ID number /10.0. and to be approximated to the nearest integer Ib. If your id is (ID = 34802 , W = 3480 lb. ) If your id is (ID = 34916, W = 3492 lb. ) 1- The force required in the hydraulic cylinder (F,) to keep the platform in the position shown... 2- The reaction forces at the joints A, B, C.
