LBF (102BeD) ame: Kon Kim Hon Class: A An air handling unit (AHU) motor in a hotel consumes 32 KW of real power and being supplied with 35.5 kVA of apparent power, Determine; (a) the reactive power drawn by the motor, (Ans: 15.37 KVAn (b) the power factor of the motor, (Ans: 0.9014 ) A PVC wastewater sewer pipe with an inside diameter of 375 mm has a slope of . Calculate the pipe's full flow capacity in (accurate to 4 dec .pl.). Manning's roughness coefficient for PVC is 0.010 . Determine the slope required in (accurate to three decimal places) for a 750 mm diameter PVC wastewater sewer, to achieve a full flow velocity of . Manning's roughness coefficient for PVC is 0.010 . A new residential subdivision is estimated to have a peak sewage flow rate (Q) of . The proposed concrete wastewater sewer carrying sewage from the subdivision drops 0.622 m in elevation over a distance of 285 m to connect to a larger sanitary trunk sewer. Determine the EXACT diameter in mm (accurate to the nearest mm ) of sewer pipe required to carry this wastewater. Determine the full flow velocity of wastewater (accurate to 2 dec.pl.) in a concrete sewer with a diameter of 425 mm and a slope of . A new residential subdivision is estimated to have a peak sewage flow rate of . The proposed concrete wastewater sewer carrying sewage from the subdivision drops 0.622 m in elevation over a distance of 285 m to connect to a larger sanitary trunk sewer. Determine the EXACT diameter in mm (accurate to the nearest mm ) of sewer pipe required to carry this wastewater. EXERCICE 4: Un multimètre numérique possède les caractéristiques suivantes: - calibres : 16 bits; 1. Pour chaque calibre, indiquer le pas du CAN de ce multimètre. 2. Pour le calibre , le multimètre affiche une tension de . a. Ce format d'affichage paraît-il approprié compte tenu de la résolution du CAN? b. Évaluer l'incertitude relative, due au pas du CAN, portant sur une mesure de Donnée: avec le nombre de bits du convertisseur Pouer facter is the effleient of the mpter. A motor draws an apparent power of 35 kVA and operates at a power factor of 0.92. Determine the eral power and the reactive power drawn by the motor. Formula: Power factor = Real / Apparent power App Power Real Power Reactive Power A motor draws an apparent power of 35 kVA and operates at a power factor c 0.92. Determine the real power and the reactive power drawn by the motor. Formula: Power factor Real / Apparent power App Power Real Power Reactive Power [4 marks] O1PEE (DEBF1) ¿Qué tipo de procedimiento se emplea para obtener los cálculos de momentos de inercia?
