Which of the following explanations is correct for finding the resulting displacement?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).

In which of these cases are the two wave points considered to be in phase with each other?
