there are tachometers available in the market with usb port. you can attach usb to serial port to get the output via serial port so that your coding becomes compatable with the hardware.
hello!
i have calculated an engine power of a prototype car by calculating the power losses against road gradients, air drag and rolling resistance. i have calculated these losses for max. car speed,lets say 50 kmph. what i need to know is do i need to consider acceleration allowance even when...
hello!
i want to calculate th total drag (surface and pressure drags) for my prototype car, a project of shell eco marathon. Actually our prototype has the shape of an airfoil, its quite stream line.the Cd we use is 0.04 which is used for streamline shapes. ihave calculated the pressure drag...
Hello!
Actually i want to find the required power of an a single cylinder air cooled 4 stroke OHV engine. i have calculated three power losses, power loss against road gradient (Pg), rolling resistance (Pr) and drag (Pd) using the following formulae:
Pg=M*g*v*grad=1.095 hp
M(mass of the...
thnx for ur response.this is basically a school project and we have to build a three wheeler car, 2 wheels at the front and one at the rear and it is to be driven at 30kmph.thnx a lot once again.
