Consider a very small particle of mass, m, dropped in a fluid. The particle experiences a drag force, FD. The constant that relates the drag force to the velocity V is K. Determine the distance covered as the partcile accelerate from rest to 50 percent of its terminal velocity, Vt, in terms of K, m, and acceleration due to gravity, g.

Hello! do you know how to save the output file of result in Ansys fluent 15.0 ? Because I want to save the number of nodes with the values of the velocity, pressure, temperature,etc. After I completed each task, so I want to save all these data and I want to compare the results with the next calculation. Thank you in advance! really appreciate you help! I will thumb you up!

An external gear has a module of 4, 52 teeth in the gear, 28 teeth in the pinion, a pressure angle of 20°, pinion rotational speed of 1500 rpm, face width of 20 mm, and gear and pinion material having modulus of elasticity of 206 GPa and Poisson’s ratio of 0.3. The Hertzian contact pressure is 0.980 GPa. The lubricant used has an absolute viscosity of 0.3 Pa-s and pressure viscosity coefficient of 2.2 x 10^-8 m²/N. The root-mean-square surface roughness for both the pinion and gear is 0.1 µm. Determine the following:

1. Transmitted power
2. Minimum film thickness
3. The film parameter

Determine all possible two-stage compound gear combinations that will give an approximation to the Naperian base 2.71828. Limit tooth numbers to between 18 and 80. Determine the arrangement that gives the smallest error.

Could you use mathcad since my professor is suggesting it with the code?

A parachutist whose mass is 65 kg drops from a helicopter hovering 2000 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the​ parachutist, with the proportionality constant b₁ = 20 ​N-sec/m when the chute is closed and b₂ = 90 ​N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 25 ​m/sec, after how many seconds will the parachutist reach the​ ground? Assume that the acceleration due to gravity is 9.81 m divided by sec squared.
The parachutist will reach the ground after
_______ seconds.
​(Round to two decimal places as​ needed.)

How to choose the suitable Heat sink from fluid flow analysis and thermal stress analysis by observing the temperature solid and liquid?

Please explain me in detail

If the device need to be used at the extreme temperature of 50 degree celsious. Based on heat source value, what is the best heatsink to be used and recommend the axial fan that suits in this extreme condition ?

A single stage double acting air compressor delivers 5 m of free air per minute at 1 bar and 20 C to 7.5 bar with the following data;R.P.M. = 300; Temperature rise of air during suction stroke = 12 C ; Clearance volume = 5% of stroke volume; Index of compression and expansion, n=1.3; Length of the stroke = 1.3 times the cylinder diameter.

Calculate: 1. Power input to the shaft; 2. The volumetric efficiency; and 3. The cylinder diameter

Please create a presentation slide about five (5) vibration control examples for home appliances.
The presentation slides must be in Microsoft PowerPoint (*.pptx) format.

Three rotating masses A = 7 kg, B = 12 kg, and C = 11 kg, are attached to a shaft with their centres of gravity at 25 mm, 55 mm and 35 mm respectively from the shaft axis. The angular positions of B and C from A are respectively 90^o and 150^o measured in the same direction. The distance between the planes of rotation of A and B is 1.75 m and between B and C is 2

m in the same direction.

Determine the magnitudes and angular positions with respect to A of two balance masses, each with its centre of gravity at 35

mm from the shaft axis, to be attached in planes midway between A and B and between B and C.
