    Fluid Mechanics Question: Calculating Pressure for Inlet and Outlet of a Bend

    You don't need to use P=F/A. Pressure at the inlet is given. You should use Bernoulli's equation to find the pressure at the outlet. Since velocities are needed in Bernoulli's, you have to calculate the inlet and outlet velocities. These can be calculated since you know the inlet and outlet...

    Finding the time constant of a thermometer

    The time constant of a thermocouple is to be found by exposing it to a step change. Then the thermocouple and a thermometer are exposed to a ramp function and measurements from each are taken simultaneously. The time constant and its uncertainty for the thermometer are to be found. I...

    Programs Need major help picking engineering discipline

    Thanks for the responses. I took a look at ECE courses and for the most part they don't seem too appealing to me. So I'm leaning more now towards ME or CE, as they sort of look like I would enjoy the courses more. I think the diversity of ME is drawing me in. There is also a biomed option in...

    Programs Need major help picking engineering discipline

    I'm in my (general) first year of engineering and I have to now decide which discipline I want to go into. I need some major help with this though because I am so confused now more than ever. I'm not even too sure that I want a lifelong career as an engineer. I've ruled out ChemE, so basically...

    Find log_x(4) as x-->1: Understanding the Limit of logx(4)

    So even with \log_x {4} = \frac{\log 4}{\log x} it looks like the limit does not exist because when approaching 1 from the left the denominator is a very small negative number making the limit negative infinity and when approaching from the right the denominator is a...

    Find log_x(4) as x-->1: Understanding the Limit of logx(4)

    Thanks for the response, now I remember that I'm not looking for the value at 1, so that makes sense now. But I'm not sure what to do with that binomial as we haven't covered binomial formula. I tried thinking about it with RHS and LHS limits. If you're approaching 1 from the left then y is a...

    Find log_x(4) as x-->1: Understanding the Limit of logx(4)

    Homework Statement Evaluate lim x-->1 logx(4) The attempt at a solution I can't understand this because basically if you plug in 1 as x, log14 doesn't have a solution because 1 to the power of anything is just 1.

    Velocity and acceleration of two objects

    Homework Statement A car is traveling on cruise control at velocity v1. Ahead on the road, a distance x away, a truck is traveling at a slower constant velocity v2. What is the maximum constant acceleration the car needs to avoid hitting the truck? Homework Equations The Attempt at a...
