How do you calculate cooling capacity of a heat exchanger? Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per […]
What is the human cause of climate change?

What is the difference between chyme and bile?
What is the difference between chyme and bile? Chyme is different from bile because chyme is actually mixed with bile to lower its pH. Chyme is found in the stomach (it is the partially digested food) and the bile can be located in the liver. It helps to digest the food. What nutrients are absorbed […]
Why is it important to reduce energy usage?
Why is it important to reduce energy usage? First of all, reducing energy use limits the number of carbon emissions in the environment. In turn, conserving energy produces a higher quality of life. Reduced emissions result in cleaner air quality. In addition, it helps create a healthier planet, or at least helps sustain the resources […]
What is the difference between potential difference and current?
What is the difference between potential difference and current? **Current vs potential difference: **The current is a flow of charge. Current is measured through a component. Potential difference is the energy used between two points in a circuit, therefore it is measured between two points either side of a component. Which instrument used to measure? […]
