For a function f, we know that the derivatives f^n(0) are non-zero only when n-1 is a multiple of 4. using richardson's extrapolation, find a formula for f'(0) adapted for this function with an error of at most o(h^10)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
