    Minimum reliable SPI clock speed MPC3008 ADC

    I am setting up a circuit for reading a 10k type 3 thermistor (10kohms). I have an MPC3008 ADC I will be interfacing with an AVR/Atmega644P microcontroller. Why does Microchip recommend higher clock speeds for higher Vdd? I came to believe higher operating voltage allows higher ADC clock speed...

    Calculating flow through (heating water) coil given only pressure drop and coil measurements

    I have a Titus DESV-06 with a single-row heating water coil and would like to be able to calculate flow rate in real time using information supplied by two Dwyer pressure transducers (one at inlet, one at outlet). I was not able to locate a manufacturer table. I will attempt to get the...
