Final answer:
The main thing to watch for when transporting concrete is the pressure at the pump. It is crucial to ensure that the pressure is maintained at the appropriate level throughout the transportation process to keep the flow of concrete smooth and efficient.
Step-by-step explanation:
The main thing to watch for when transporting concrete is the pressure at the pump. In this case, the pressure is given as 8.00 x 106 N/m². This pressure is important because it determines the flow rate and resistance of the concrete. It is crucial to ensure that the pressure is maintained at the appropriate level throughout the transportation process to keep the flow of concrete smooth and efficient.
