DRAG ON SPHERE & TERMINAL VELOCITY


The drag of a Sphere. The aerodynamic drag on an object depends on several factors, including the shape, size, inclination, and flow conditions. ... Where D is equal to the drag, rho is the air density, V is the velocity, A is a reference area, and Cd is the drag coefficient. Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration Most useful and reliable A textbook of fluid mechanics by Dr. RK Bansal is available at https://amzn.to/3keCpcZ

  What are the different types of dams? Arch  Dam. A concrete or  masonry  dam, which is curved upstream so as to transmit the major part of the water load to the abutments. ... Buttress Dam. ... Coffer Dam. ... Diversion Dam. ... Embankment Dam. ... Gravity Dam. ... Hydropower  Dam. ... Industrial Waste Dam. Which is the biggest dam of world? Three Gorges Dam Three Gorges Dam , China is the world's largest hydroelectric facility. In 2012,  the Three Gorges Dam  in China took over the #1 spot of the largest hydroelectric dam (in electricity production), replacing the Itaipú hydroelectric power plant in Brazil and Paraguay. Which is the longest dam in India? Hirakud Dam Hidden Worlds And Stories Of Progress At  Hirakud Dam , Odisha.  Hirakud  is the longest earthen Dam in the world and stands across the mighty river, Mahanadi, in the  Sambalpur  region of Odisha. It was the first major multipurpose river valley project after Ind...

                                                                     Hydraulic jump practical part-1 Loss of Kinetic Energy. The velocity of subcritical flow is less than supercritical flow. The depth of subcritical flow is greater than the depth of supercritical flow. Calculation part For discharge= Q= volume/time Q= A * V Q= b * Y1 * V1 Q= b * Y2 * V2 Fr1 = V/ root ( g*y1) loss of enenrgy= (y2-y1)^3 ------------- 4y1*y2 A hydraulic jump is a phenomenon in the science of hydraulics that is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface. Types of Hydraulic Jumps – Based...

This post is about  Civil Engineering Interview Questions What made you decide to become a civil engineer? This question allows candidates to explain their reasons for becoming a civil engineer. The answer will be unique to individuals and will give you insight into what inspired them to choose this career path. What to look for in an answer: A genuine answer that reflects a true passion for this career path An unhurried reply that shows that the answer was well thought out Example: "I decided to become a civil engineer because of my father who is a Math teacher. As a child he shared his great love for solving mathematical equations and other types of puzzles with me. He was always asking me to look outside the box to solve each dilemma. He encouraged me to have a quizzical mind and to always explore not only how something was built but also how it worked. He inspired me to figure out if the design could be improved upon by utilizing a different means." Why should we hire you...
