transfer is....... Q4. Specific heat depends on these two parameters... Q5. 10 g of water in a closed system has internal energy changed from 20 KJ at temperature 50 °C to 30 KJ at temperature 70 °C. The specific heat of water will be ***** we Q6. Heat transfer rate is defined as Q7. 100 KJ of heat transfer for 3 hours through a surface area of 1.5 mm², then heat flux is Q8. At steady state process, the rate of heat transfer to the system is not same as the rate of heat transfer from the system (True/False) Q9. Volume flow rate of a fluid in a pipe is same as velocity divided by cross sectional area of the pipe (True/False) Q10. Mass flow rate is product of volume flow rate and cross sectional area (True/False)
